How do I reset the Transmission Control Module

[highace]

How do I go about resetting the TCM on a 5 speed auto? I'm getting strange shift patterns atm.

I've changed out the transmission filter and all new fluid as well.

Cheers

Tech2, or another type of Diagnostic Unit I am guessing,
never been asked to do that yet.

I'll have to give the battery trick a crack. Fingers crossed....

What, and how much fluid went in it ?

I used Penrite ATF LV fluid and I put back in approx 4.5L, maybe a bit more than that.

One issue I had was that the car wasn't dead level when filling the fluid back up. Maybe a little nose high.

My train of thought is to reset the TCM to discount any bad habits the transmission may have learnt recently. If that doesn't change anything then ill have to look more into the mechanical side of the transmission.

Search the forum for “quick learn shift adapts” as there are dozens of threads about what to do to program / learn adapts correctly after you reset the TCM.

Thanks for the tip. Now to find someone with a Tech2 scan tool.

No need to a Tech 2, to relearn shift adapts the procedure is done in the garage all without programming.
