Hi Smaky, Thanks for the answer, everything of the above is done, yesterday I even changaed the clutch speed sensor for test but no luck, as for the EV0 it is a brand new one and tested with FES by the test max pressuere in the EV0 is 28,308 bar. few days ago I received the following errors: -clutch sensor -clutch system now suspecting on the clutch kit, my question is is it possible that my problem( clutch slip when cold and juddering when hot ) is from the clutch or can be caused from something else, clutch kit is valeo, changed 8000 km ago Many Thanks

Hi again, After few issues and right adjustment of every thing and changing and control of everything.... I have a small clutch slip when the car is cold it affects mostly 3rd and higher gears, the clutch disengages with delay, when warmed properly it has no problem, this is after 350km after calibration, my mechanic says that the clutch needs to bed in, but.... Parts that are changed: -clutch 8000km ago, 3000km driven with clutch rod on 22, -all of the PF2C sensor changed with new marelli ones -accumulator changed with new one -EV0 changed, new one part number 71753760 -filter on the actuator cleaned -high pressure sensor changed, -pump checked in good working order, no problems with pressure -clutch rod adjusted on 28,035mm warm and 28,350mm cold -clutch speed sensor checked with no physical damage, meaning that the gearbox is ok, how ever the sensor had slightly darker color on top... What can cause clutch disengagement slow when the car is cold and with no problem when properly warmed, also when warmed good it has small judder on take off in start stop traffic???? Many thanks, Smaky

Ok, Thanks Smaky, now I will think for the remap, maybe I will go with full exhaust system without cats (anyhow I will not have the cats because I have new decated stainless steel manifold). Regarding the solenoid valves: 1. Is the new design of the ev0 better, worth buying it part number 71753760??? 2. Is ev0 same with ev1 and ev2, the design is the same and physically they are the same, but I have read that the flow rate is different, ev0 10l/min and ev1, ev2 7l/m. -I'm asking this because I want to put (if possible) used ev2 on the place of ev0, because they have less problems and all ev0 have problems.... Hope I was understandable Thanks/Regards

Thanks Smaky, It is a JTS engine I have read some posts and have seen on my car that jts is air restricted and also regarding the remap there are a lot positive comments about a remap on a jts....?? Before I go there it seems that I will need to change the EV0 for the clutch, it developeed (it had) a jerkiness when cold, meaning that the clutch does not engage and disengage smooth and once during driving the cluth was not engaging enuf and disengaging enuf, every thing elce is new, clutch, sensors, calibration.... Regards

The sensors (PF2C) were changed, system was calibrated and the problem is gone, 1000 km with out any problem, will see until when The biggest difference from the change of the sensors is the speed of the gear change and the noise from the actuator when changing gears. The gearchange is much faster in any rpm and the noise during gearchange is reduced a lot, and also the issue with jumping from 1st to 3th and reverse is fixed, now the car is very good to drive it city mode which was not the case before. Now I'm planing to open the box to inspect it and clean it if there is something there. Now two questions for Smaky: 1. If I open the gearbox, I know that on the back plate of the box are reverse an 5th gear, also every gearbox Alfa and Fiat regardless of selespeed or manual have problem from time to time with reverse, difficult to engage , I had 156 2.0 twin spark from brand new and I had the same problem with reverse, needing some effort to put it in reverse, my mechanic says to live it alone because is the same with every gearbox from Fiat group. My question is: can this be solved, is there any part that needs to be changed and if it needs which part it is and where can be find, since I'm planing to open the box. Hope my explanation was good. 2. There are clutch kits Drive Torque stage1 and 2 on ebay http://www.ebay.com/itm/DriveTorque-Stage-1-Clutch-Kit-Alfa-Romeo-147-2-0i-16v-Selespeed-07-02-05-05-/311340348087?pt=LH_DefaultDomain_3&hash=item487d54b2b7 http://www.ebay.com/itm/DriveTorque-Stage-2-Clutch-Kit-Alfa-Romeo-156-2-0i-16v-Selespeed-03-02-09-05-/121628025613?pt=LH_DefaultDomain_3&hash=item1c5198630d are they any good, I'm asking this because I have bought stainless steel manifold 4-2-1 without cats and after this I'm planing to remap it and change the induction pipe from one from 2.5 v6 or gta.. so If I'm doing some modifications it is good to do some for the box, but the question is are those clutch kits good.... Regards

Dear Smaky, I have tried to find some mechanic who is willing to open the back casing on the gearbox and check the clutch speed sensor, but no one wants to do it all do is a very simple procedure... also there is no noise from the box at all, until I find some one, no thing on checking the box. If I do it I will make a update. I was also checking this days shifting when engine of, from time to time when sifting from 3rd to 4th, it does not engage 4th instead drops in 1st, also some time skips 4th and goes into 5th... but this is not constant it happened 3 times in 20 shifting. Also some times the car drives with no problem, the problem with engaging 2nd and reverse is from time to time, and also two times I had a problem with engaging 5th during driving. I will make an update when I change the sensors and if I have a luck to check the box, I hope it will be help full for selespeed drivers the solution of this issue. Thanks/Regards

Hi Smaky, I already ordered three of the sensors and I'm planing to change them all of them for safety reasons. How ever until I receive the sensors I drive the car, beside the problem I described above today some thing new happened and maybe this is directly connected to the clutch rod sensor, the car engages all gears but when it change gear it is like the clutch pedal is still pressed (like on a manual ), when you are at a stand still it changes gears like the clutch is not pressed enuf, and the car goes with out pressing the throttle paddle with 1st and reverse until I press the brake paddle. Can this be caused from the sensors? or is some thing else.... -Clutch kit changed 3000 km ago -accumulator changed -No liking -Pump working good Thanks/Regards

Today again the same problem after EOL calibration and two days good driving with out problems, not engaging 2nd skipping to 3rd, or engaging 2nd with delay and few attempts from the actuator and after this issue engaging reverse but the car is not moving ( I can here the actuator engaging and the display says R but the car is not moving) ..... My mechanic who has worked in Alfa service is confused and by his opinion some of the PF2C sensors makes a problem, I already ordered 3 of them. Also I'm confused and my question is, if I'm on the right track? Can these be caused from the from the sensor, how ever the problem gets more frequent..... Thanks/Regards

Un update, Smaky you were right THANKS.Today I went to my mechanic ready to do the pump..... after checking for error codes it come out p1818 gearchange control, after thinking for a while he told me that he didn't do the EOL calibration AFTER ADJUSTMENT of the rod to 28,182 mm, after that he run EOL calibration or (Production/Final calibration) and we went on a test drive to monitor the pressure, the pressure was going from 37 bar min. to 50 bar max. during gearchange and there were no problems what so ever, every think ok with the pump...I didn't drove a lot somethink like 50 km today but with out any problem, no going in neutral, no stuck in gear... 500 km and again check if everythink is ok. The clutch was not ADJUSTED like it should, how ever I will monitor the situation and make and update. Thanks and Regards

Thank again Smaky, I really appreciate, The hose was changed after the clutch( for how long it has been there I don know, I know that I have drove the car with hole in the pipe for 5k km) The level of fluid is correct, changed ( Tutela CS speed ) also the accumulator was changed with new one. The clutch rod was adjusted ( Thanks to You ) on 28,182 mm and final calibration, after driving 800km the rod is same 28,182 mm, there is no change at all, which it surprised me in a positive way.( this adjustment makes BIG difference ) Clutch self adjusting was done but I'm not sure that was successfull, in the FES that my mechanic has is a procedure with 1st gear, 25% throttle, 300 meters, not the procedure that is with 2nd gear up to 3000 rpm... How ever today city driving every thing ok until parking, I needed to do few maneuvers with 1st and reverse, the third time with reverse the car was stuck in reverse for 5 seconds( I was trying to sift in first with no success ) after that I moved the gear lever in neutral and it went in neutral but was not engaging gears, after this I was shutting the engine down and I heard the pump prime but with delay, when I heard the pump I restarted the car instantly and there were gears . On my way back everything was ok no problems. Again the car was left for 48 hours, pump prime time ok, but the sound of the pump fading... I'm suspecting on the pump or the pressure sensor ( something connected with the pressure in the system ) or clutch adjustment which I do not know what is the right procedure, I suspect that this was never done from the previous owner.... My Regards

Clarification when I say "noise from the gearbox"(in upper posts) I was referring to the actuator working trying to put it in gear (clinking), how ever I didn't had any noise coming from the gearbox I'm referring to the actuator. Sorry!

If the problem is like you describe in order to be sure 100% should I look for oil liking in the gearbox? Thank You

Dear Smaky, First of all thank you for the reply! The past few days the car is working ok, as for the clutch kit it was changed 2000km ago with original kit, how ever I was driving the car with a hole in the high pressure hose that is going from the pump to the actuator do to the pump was priming more than it should other symptoms are: -when in neutral the pump primes from 41bar to 47 bar and holds the pressure for 10 min, it primes to 50 bar when doing gearchanges with the engine off, -when I open the door the pump starts but the volume of the sound is fading, on the start is higher and fades to the end, From what I have read the pump needs to be changed when you change the clutch, my point is if the pump is on the end of the life can be this caused to fail with priming from time to time? How ever on Monday I have appointed with my mechanic and we will check every thing with examiner FES and I will post the details of the outcome. Thank You/Regards

An update, and please any ideas or help, Again on a trip and this time donwshifting from 3rd to 2nd and there is noise but no 2nd gear instead 4th and then 2nd with a selespeed system failure, when I arrived went to the mechanic to check the car and this were the errors: 1. p1753-acoustic signal 2. p1818- gearchange control 3. p1744-hydraulic circuit pressure sensor- for this was the signal on the dash How ever I also checked how the pressure goes it was from 40-50 bar, when in neutral the pump primes after 5-10 minutes. However in the next few days the problems were much often not going into gear on up shift downshift going into neutral etc. Today I have cleaned the connector of the hydraulic pressure sensor, I have not drive a lot, also it was not for cleaning like a soo... but it seams that the problem is there. I was shifting gears with the engine off there is some delays in engaging, but it does engage every gear... I would appreciate your ides as I like the car and I want to keep it, when is working good the selespeed system is nice and I like it.... Thanks

Update of the above issue or additional problem While driving on a open road to a other city before arriving, 5th gear downshift for 4th, the actuator trying to shift to 4th(I hear clinking noise) and drops in to neutral, I stop the car and restart it there are no gears, I wait for few minutes and restart it and there are all gears, but there are problems with the downshifts with the gears and no reverse after the restart and few km driving. I finished my job and going back home, there are no problems what so ever, as a test I preformed few, three or four hard takeoffs with all gears, changing 1st 2nd 3rd on 6700 rpm, with no problem and the shifts were very quick. And something that i forgot to mention in the earlier post, my mechanic has a FES where clutch self calibration is with 1st gear and driving with 25% throttle for 300 meters no like the other procedure with 2nd gear with full throttle up to 3000rpm, any how after I changed the clutch kit this procedure was not preformed, we have try but without success. My questions are: 1.Will this procedure (clutch self calibration) work with 1st gear because from reading other posts most of the people that have done it say that is not working. 2.Is it recommended to clean the clutch speed sensor and do the calibration. 3.And final what is your opinion for my problem, I really appreciate your help and opinion, I don't want to mess in the system in a wrong direction and make a bigger mess. Thank You a Lot
