Hi everyone, I am fairly sure I have problem here but the question is how serious is it?

I have had my 147 now since about feb this year. Once or twice I noticed a slight (1 maybe 2 sec and its always the same amount of time) delay when selecting reverse upon first starting the car (I think it may have happened once with 1st but cant be sure).

As it happened so rarely I didn't think much of it. However this last week its happened 3 or 4 times. What seems to happen is after starting the car I select reverse there is a slight delay or perhaps a second maybe 2 then I hear the clunk, R will show on the dash and the beeps will sound. It seems mostly to happen after the car has been park over night or all day but I have had it happen once in the morning after stopping the car for 5 - 10 minutes. The pump seems to be fine, it pressures up when I open the door and the sound seems to be quite consistent.

The car has only recently been serviced, my mechanic did say there was a selespeed fault logged, however he didn't seem to concerned and cleared the log and it didn't reappear for him. He didn't write the fault down so without speak to him I can't remember what it was. I have checked the selespeed oil level and it seems to be fine. Battery was changed in June 08 so I don't think that is a problem.

The car seems to drive fine otherwise, it is not jerky and has not done anything else odd. I have had a hunt around on here, there is someone in the selespeed fyi who seems to have had a similar issue but I'm sure they had delays for up to 5 secs, in that case I believe it was the shifting sensors?? Any Ideas what this could be.

Regards

Sam

There can be a delay selecting Reverse.
The system first tries to select it normally, if it doesn't go in it tries harder (with more pressure) which is why you hear more of a clunk when there is a delay. If after (I think) three tries to select, it gives up and stays in Neutral with an error beep. You can then try again.

no, thats normal, when you have a manual you notice sometimes that
putting in reverse sometimes does not go easily or not at all, trick is pushing the clutch pedal in and out and then it goes smoothly.
Same happens with the sele,

I used to have this problem and it seemed to go away after I had the Sele clutch rod adjustment done. The mechanic hooked up the car to the Examiner box, fiddled with the rod length to get it within 28-28.5mm (previously went up to 29mm) and after lots of clacking, everything was fine.

Hi all.

I have been having these problems on and off since making the original post but have at least until tonight ignored them. however, tonight on my way home I stopped at the servo, when I got back into the car went to select reverse, it clicked and then did nothing. Tried again and nothing, no noise or anything, I then turned off the car, tried again and it worked. I then reversed back to where there was more light and stopped and checked the sele fluid level. The car has only been serviced a week ago and all seemed normal. So I started it again, selected reverse and nothing, not even a noise, I selected 1st and then reverse and it worked. I then drove home where I tried again, before stopping the car then once after stopping and restarting and both worked.

The pump seems to be behaving normally. Any ideas?

Kind regards

Sam

firstly hook up to Alfadiag and read the Selespeed ECU log ! check pressure , battery, clutch rod lenght and recalibrate..... the log will also show missed gearshifts...

I'm reliably informed that the following is what happens:

the system does not reattempt to select reverse with "MORE PRESSURE", mainly because the first attempt was probably with the system at "FULL PRESSURE" and it missed because the 5th gear lockout was engaged, the clunk clunk you hear after a missed reverse selection is the range shaft moving up to between the 1st/2nd position before going back down to the 5th/R point to engage reverse so that the lockout is released. It will then engage reverse with the remaining pressure in the system before the pump primes again. The reason all this happens is because the system has not been serviced correctly for some time.

Hi Guys,

thanks for all quick replies, much appreciated. I will contact my mechanic today and arrange to have the car tested, I may as well just about go and live there at the moment!

I couple of quick questions if I may? What is the 5th Gear lockout? Also iainfm I assume you are referring to servicing the selespeed system? Does this mean a clutch rod adjustment or calibration of some sort? Would you normally expect a mechanic to do this sort of stuff, my car has done 71,000km and was serviced just last week, I always gone to the same mechanic and have always trusted his word, perhaps I need to ask for this specifically.

Thanks again guys, it is really great that people take the time to give advice on here, especially to those of us who probably don't have a solid enough knowledge of mechanics to own such a car.

hey mate, if you don't mind posting how much your mech charged you for the rod adjustment that would be great. from aus too...just want a rough idea of price.

one thing i have noticed is that the sele will do nothing at all if you turn the key then try to select a gear immediately after.

i start mine up then wait for the revs to come down to idle/fastidle before i go for a gear, otherwise it does nothing. takes a few seconds but nothing more.

Faulty accumulator or pump possibly...getting it on diagnostics would help!

Maybe I did just try to move it straight away I have noticed that same thing with my car.

sammich, I haven't add a rod adjustment done as yet, I did get them to check it once when I had it in there but they said it was fine.

My car normally costs give or take around 400 for a service at a specialist mech here in Adelaide. Im not sure how this compares to other specialist Alfa mechs, however, the car is really starting to put a dent in my wallet!
