It just seems more than anything, that the shifts are just hard and off of the correct RPMs.

So, this is a friend’s car.

The output speed sensor g68 is the one under the gear. GLS,silver Fuel Economy: If it works thats great, just keep driving it to make sure it doesnt start to slip again. Every fresh job thats comes into my shop with the 09A, has that problem. I was going to try to recode the trans, but I guess I need to login, and I don’t know how to do that.

I haven’t worked on jtco many auto transmissions. After about 1 week if the tcu reset slip again why? All times are GMT You’ll have access to the filter while your in there.

I have seen many problems with the sensors in this transmission. Thank you so much for the great information this is just the place I was hoping to find up to now finding information about this transmission was like tryin to find the dead sea scrolls I will let jattco know how I make 009a thanks again.

I should first note that it had a bunch of electrical problems First off, there is a myriad of mistakes that could be made doing this. Yes, my password is: I only have a Bentley, and I can’t seem to find info on testing the sensors in it.

I like this pic because it gives a visual picture of the “stand pipe” that allows you to check the level. Why does it work fine when you reset the TCM?

All you really need to do is split the case with jtaco trans on the bench with the bellhousing facing up.

So you get a once in a lifetime opportunity to change the filter!
