hope some of you fellow owners find it usefull!

Absolutely superb stuff! Nice one!

Thanks for that. Only read the intro so far, really well explained, can't wait to get some time and get through the rest.

Great to see this information. Have been experiencing bunny hopping on take off. Only on hot day 30 degree celcius approx(outside temp).

Have been reading this info and have a few ideas now. Thanks

Great site!!

Working my way through but very comprehensive and well laid out.

Many thanks

Thanks for that - very interesting indeed...

Reading through it, i've noticed that any faults detected are always accompanied by a warning. Mines playing up (sometimes slipping into neutral and not possible to change gear when i come a to standstill etc) but no warnings whatsoever.

I know that the system is registering and displaying faults as i can generate a 'selespeed fault' by keeping the gearstick active for a few seconds...

Anyone heard of selespeed faults that cannot be detected by the gearbox ECU, and hence no warnings?

Yep, mechanical faults in the gearbox.
Low pressure won't log an error either, but it will flash the warning light.

Hi, My selespeed gearbox was renewed and the actuator started to leak. Anyone have any ideas? Thanks in advance.

Hi, Can any tcas147 get in touch with me? Sent an email to the contact me email on the selespeed website but no reply yet. Hope to hear from you soon tcas147, want to ask you if it is possible for an actuator to leak from one of the petentiometers?

Thanks, Dan

My 156 Selespeed also kept going into neutral with no warning light. Never have got to the bottom of it - after the examiner was used it highlighted a few dodgy relays, and a recalibration was done after a rod was adjusted.

Problem still occurs, but much less frequent - no warning light. No sign of leaks, pressure is fine after pump was replaced.

I just saw there is an entry on the Paul Denyer web site for "Manual to City changeover uncommanded" which is the selespeed problem I have encountered on my GT. It's happened about 4 times since I got it 3 months ago and I've only done 1500 miles. It's nearly 3 years old. This never happened on my 147 Selespeed whch I had for 5 years before the GT.

Unfortunately I don't understand the details on the web page. Is this something that is considered normal or OK? What causes it ? Does the car need any adjustment to prevent this happening or is it something you just have to live with and reboot the car when it happens because you can't get it back out of City mode in my experience (or into N or R)?

Any help would be appreciated as the garage don't know what to do with it and they've had it twice now for investigations!!

Thanks

change the battery it makes an instant change to the way the car responds i had the same sort of problem myself i changed the battery and its been perfect ever since

Thank you!! This saved my life and some money too!!! x

Sorry, Ruby Boots, are you meaning the old battery Bogeyman got at you.:

First thing I got, was a new battery, of the correct capacity??? (the incorrect one was fitted: ) all sorts of flashing messages, Oh! and a new transverse link.:

Hi. my car slips to neutral on standstill at traffic light. would changing battery fix this problem? coz with diagnostic tool, it wont show any fault codes...

What is the exact battery voltage after the car has been standing overnight?

I dont think you have a problem, this is normal behaviour.It is supposed to automatically change to neutral if the car remains stationary for more than a couple of minutes to save wear & tear on the clutch actuator.
If you are going to be stationary for a while, best to drop it into neutral yourself. That way you know where you are and removes the embarasment of going to pull off and all that happens is you rev the nuts out of the engine

I'd understand if it drops to neutral after couple of minutes but it changes as soon as i completely stop at traffic or whereever.. it should hold at 1st gear for a minute or even 30 secs but it wouldnt.. it wasnt like this b4.. i didnt need to put into 1st gear at traffic to start.. it would move as soon as i release the brakes.. but now i have to move my arm.. help somebody.. what is wrong with my car?!?!
