Hi all,just started up my beloved 75,2002,auto,diesel and it literally jolted into gear when put in drive.didnt think too much of it as it sometimes does that when cold.but thinking about now,never like it did then...driving along and the whole car jolted as it went into 2nd...drive it about and it's basically jolting through the gears and almost like a mini "engine break" type thing when changing too.absolutely the wrong time for me to have some major repairs done.iv heard it maybe a fluid problem or solenoid problem? Read on another post where someone said it could be fluid and if it is it's too late as the damage is done?any advice would be very much appreciated and thank u in advance!

Forgot to add that it came on suddenly,no warning or indication that there is a problem

That will be your 2/4 duty brake soliniod

Have a look in how to section under jatco auto box


It's a simple job and needs a few basic tools to do the job

Alan123 thanks for the advice mate,I'm a fairly new when it comes to the old diy car repairs,worth a trip to the garage or is it really that simple? Least I can tell them exactly what the problem is anyway!

On another note,would that show up a diagnostic check?

Just be careful with garages they usually tell you it needs a new box

But the box doesn't have to come out just have to take inspection cover off the front of the box
But do take time to look in the how to section it is very helpful

Seriously mate it is a simple task
And if you jack it up slightly you won't loose any box oil when you take cover off.

It generally shows up as a fault on T4, you can also check the resistance of the solenoid at the main connector under the bonnet

Thread moved to a more appropriate forum. Re-direct left in old. This may be the better forum as threads get ‘lost’ very quickly in the General Forum.

Just an update really,went to a mechanic mate of mine that I trust,who plugged I his diagnostics equipment and it said,as you've all correctly predicted,that it's the 2/4 brake duty solenoid....sourced a replacement which will be here 3-5 days and cost a little short of £80...only thing is now,the mechanic hasn't done a job like that before,so I'm going to have a go myself.can anyone send me a link to decent "how to guide?" Please?all your help has and is Much appreciated guys,thanks again,will update how easy or hard I found the job!
