TB42 Auto box Electricals?

[taslucas]

Sounds a bit odd, so what was said about the engine speed sensor? Also, like me, have you changed the coil lately by any slim chance?? Tachometer steady and not bouncy at all anywhere through the range?? You said you ruled out the TPS so that is about all I have based on the issues I've been having also ...

Good luck!!

Just thinking the speed sensor may be giving an erratic signal. Nah havent changed the coil, tacho only bounces as the torque converter locks then unlocks, locks then unlocks etc. Yeah TPS is ruled out.

Cheers

first thing that came to mind was electrical loose conections or faulty soliniode
then todd mentioned gear shift might just be the button again electrical

glad i went back to manual

Another thing I would check is the temp sensors on the valve body, when I had problems with my gearbox I found one of the wires on the temp sensor was broken.

Definately more things to go wrong in an auto, but its not common for patrols to have this much trouble. Bad luck i suppose. Auto's are great for Mud hills, Sand, Rock steps....everything except down hills and simplicity!!! lol
Very close to biting the bullet and fitted the extreme valve body while its apart..........But still will have to fix the problem

Mate, I just installed that valve body, so when I get mine back and its actually running like it should, I can update on performance ...

And the downhill bit is more than solved with reduction gears - single best investment I've made (better than lockers for the amount you use them) ... mine crawls down hills now and if you get that valve body, you can get the manual torque converter lockup switch also and use it for engine compression down hill ... not as good as reduction gears, but a damn site better than standard.

Thanks mate, i think ive skipped to steps 3 and 4 where it says: dissasemble A/T and check torque converter and oil pump.

Yeah i think i am sold on the new valve body. Dont know about reduction gears tho, i like to floor it a bit sometimes!! But i look forward to hearing about the difference in your performance

Looking forward to having it all tickety boo myself mate ... will update though ...

Been talking to wholesale automatics they are nearly %100 certain that it is the temp sensor. I'm going to exchange the valve body for a extreme stage 2 and they will fit it with a new temp sensor. Fingers crossed it will fix the problem and be better than new!

hope so mate best of luck
