Log in or Sign up Close Panel. Results 1 to 20 of I have the following problem and that turned my automatic from 3 to 4 gang rough. If the Automatic TCU unit reset it works perfect for 1 week.

The transmission has about 15 thousand kilometers. Air mass meter is new! Sponsored Links Remove Advertisements. Do you mean this trans has a rough shiftdoes is it maybe a slide bang shift?

On the 09A or JFE, the common problem with those when that happens, is the high jwtco piston cracks, thats why the clutch burns out. Sometimes you can see the crack when its bad, but most of the time its not visible.

The drum that houses the piston is right behind the back cover. They are replaced as set high and reverse clutch piston. If your going to do this yourself be careful with the clutch i believe there are 2 different thickness on the high clutch. If it works thats great, just keep driving it to make sure it doesnt start to slip again.

In my opinion, im still going with a cracked high clutch piston. With a little finesse, you can take the back cover off, drum is right behind the back cover, check the high clutch, if its bad the pistons are cracked.

As i said before thats the 1 problem with this trans. Thats what i see here in new york. Every fresh job thats comes into my shop with the 09A, has that problem.

If you want to fix this yourself, be careful, there are 2 different thickness high clutch packs There are 2 sets of clutchs in the jatck high and reverse, the high clutch is the smaller clutch. At the begining of the thread you said that the transmission has a rough shift jatc 3 to 4. Why does it work fine when you reset jaco TCM?

To answer this, you will have to jjatco a scan of the TCM when your transmisison isn’t working properly. When TCM detects an issue not all issuesit goes into limp mode and high pressure is applied.
