i recently had my transmission rebuilt by my father who is a retired transmission man and my husband who is a mechanic. The transmission did good for a week then all of a sudden started shifting gears hard and it gets stuck in second gear and I can't go past like 35-40 miles per hour. The RPMs have been floating a little here and there and everything that I have read and heard was pointing to the throttle position sensor but we just replaced that and took it for a test drive and it is still doing the same thing.. I need help. Any ideas?!?

 

Have you had your father and/or husband look at it? Since they rebuilt it,. they may know whats wrong.

 

What engine/tranny combination are we talking about???

 

Yeah they’ve looked at it and I’ve even had another transmission man look at it but I haven’t heard anything back from him wondering if anyone else has had the same problems as me and what they did to fix it

 

V6 and tranny is 42RLE

 

Do you have any codes?

The governor circuit is common to both your problems but could also be a valve body issue.

 

We just redone the valve body and put a shift kit in it and it is still doing the same thing. It gets stuck in what seems like second gear and won’t go no higher than like 35-40 mph without reving up

 

 

So are you saying it won't shift into 3rd at all? or it will shift into third eventually at a high RPM?

Can you you get your father and husband to elaborate on what was rebuilt/replaced in the transmission? Why was it rebuilt in the first place? What was wrong with it when it was torn down? I assume the pan has been off since it was rebuilt and your last posting of 11/20, Was there anything in the pan? Was the TC replaced? Was the Overdrive unit rebuilt?

Does reverse work? In order to shift into 3rd, the front clutch and the rear clutch are needed. Since the rear is used in first and second we can assume that is working. The front clutch is only used in reverse, 3rd and 4th.
When they rebuilt it did they do an air test on the clutches?

When the valve body was "redone" did they pull all of the vales out and check the bores for wear? what about the governor bores? Have you done a pressure test on clutches using a gauge and the case plugs for each of the clutches?

Sorry for all the questions but a transmission has a lot of different parts and each part has a diagnosis to it that helps narrow down the answer.
