selespeed woes!

A few weeks ago the change from 1 to 2 jumped into neutral and then all was ok for about a week. Then it did the same and refused to run in anything except first or (sometimes) second. At the same time reverse would only select after first gear but not from neutral and then did it with a bit of a thump. At first, the gears were all available in MAR but then only first, second and reverse but intermittently. The pump runs as it always has and I was advised to change the accumulator-no difference. I have had the car towed of to a local workshop as I suspected a gear position sensor was duff. The garage said that this showed on their diagnostics and changed it, but then got the same error messages! They have played about with swapping sensors and doing some wiring checks but are stumped and I am getting the car trailerd back to my home to see if I can do any better-fat chance! Expert help is rquired - I live in Swansea and don't have any local Alfa dealer or one I would trust

Check the selespeed fluid level, the clutch rod length and recalibrate the system.

Are there any strange noises though that have started recently in the engine bay?

Pump seems to run as usual 8-10 secs on door first being opened and cuts in after 2 or 3 attempts at gear change for a few secs. I can hear and see the clutch rod moving and sometimes the gears will select with ignition at MAR but not all the time. With the engine running no gear will select - sometimes 1 flashes briefly before N comes up and there is a single bleep. There is no selespeed warning light showing and the fluid level has never been low when I check it each week when I check the oil. The clutch was supposedly set and a recal done by Rusper Alfa a year ago- about 6000mls back and I have just done an engine and gearbox oil change - gear oil looked very clean and I found only minute bit of sludge on plug. The car is a 51 plate with about 65000 on the clock all by me!

I dont have any way to recalibrate the system as the car is now back home after my nearest garage gave up on the problem before the IMF had to bail me out! They said there were a feww error codes, but the only one they seem to have recordrd is P1742 selector range sensor, if that helps. Is there any other way of setting the clutch?

Thanks for replying, Ralph

OK the range sensor is the one on the back of the actuator, for the sake of testing you could swap this sensor for one of the 2 on top and try the gearchanging again,

Also, can you select all gears when the engine is not running?

I suspected that rear sensor as I managed to get an Ohmeter on it and it seemed to have different readings to the other two. The garage I took it to had a Bosch analyser which they said was talking to the system and gave a P1742 error and they put a new sensor on -the one at the back but then they still had errors but did not record the error codes! The mechanic recalled them being P1743, 1748 or something similar.

When the problem first started I could select all gears with the engine off but now they will not engage except maybe one try out of ten or twenty.

Have just been out to try and not able to select any gears with engine off or running -tried about twenty times.

Smaky,

Have just seen your response to Brackenfox about swapping the top two sensors and poss clutch bearing problem - was that reply meant for me or am I just being stupid, again?!

Ralph

It pretty much stands for both of you.

Also the Bosch kit is rubbish on Seles, it's software was copied from the examiner and that is crap for this too.

If your not too far away I can get over and look it over to see what's up with them

As I don't have access to any diagnostic kit, Iswapped things around as you suggested and nothing changed so I just experimented with adjusting the clutch rod length a bit at a time and then trying to select gears and it worked!! I can now select all gears with engine off and having started the car with jump leads from the battery sitting on a bench beside the car I can get 1,2 N and R as it should be. there is no graunching or jerking when gears engage but I will have to wait till tomorrow to get it all back together and see if it drives. Will it be OK to drive it without calibrating the system? My nearest Alfa specialist is In Cardiff which is 45 - 50 miles from my home in Swansea so I could take it there if it won't damage anything. I am quite hopeful that you have identified the problem and I am very,very grateful to you,

Many thanks, Smaky - you have a friend for life!

Gratefully, Ralph
