Default Auto tranny issue now

Hey again guys,

Just when my engine is running nice I started with tranny issues.

2001 non turbo. Just today I felt heard something from the tranny on deceleration. Sure enough it kept happening. Going from second to first it shifts rough.

My motor mounts are good.
My fluid was slightly low.
Changed filter and fluid 28,000 miles ago.

So tonight I sucked out, 3.5 quarts. Then put back 4 quarts. Actually on the high side now. But I wanted to see if the issue went away.

It has not. Iíve been reading, maybe a speed sensor? Maybe silinoid pack? Needs a total flush? Or rebuild the tranny.

Any help guys?

Are you using the correct ATF+4 fluid? If so, you need to get the level right. Too much fluid can cause excessive foaming and the trans won't shift correctly. If that's all okay, take it to a REPUTABLE shop (NOT AAMCO) and get the CVI's checked. It might be time for a rebuild, depending on how many miles you have on it.

I would suggest taking your Pt Cruiser to a transmission shop and have them check it for transmission trouble codes. Usually they don't charge to scan it for codes. They might even give you an idea what might be wrong. Post what you find out.

Have you checked the tranny mount?

I will get a tranny shop to check for codes. Have not inspected tranny mount. But this thing is going HARD into first gear. Sure feels like tranny to me.

Correct +4. 165 miles


Is it hard to rebuild it myself? Will a rebuild kit do the trick? Or will I have to search for a bad part in there to replace!

I had a shop check the codes. First with an inova. And no codes. Then they used a better scanner, I got one code. Gear ratio error in reverse.

I though it was p0450. But maybe it was not because I donít see that code anywhere.

My reverse is fine. He also tested the silinoids and he said they open and close fine.

Any ideas guys?

This might be the code you were getting.

P0736-GEAR RATIO ERROR IN REVERSE

I unhooked battery, touched the two together. Pushed brake pedal and left it unhooked for an hour. Nothing has changed. Sometimes coming to a stop of fine. Most of the time itís rough into first gear. It does seem that itís not as rough as first.

If Iím coming to a stop I put it in nuetral. Come to a stop then put in first. No rough shift then. However I can see the revs go up higher than it should with not gas peddle presses. It seems confused.

Maybe change the speed sensor? Change the transmission computer thingy with a used one?

How many miles do you have on this transmission?
