I have a 96 z28. I just changed my flexplate. During the process, the transmission fell off the jack. Not all the way off but most. After cleaning up the spilled fluid, I did an inspection of the transmission and its wires. Everything looked good, so I put it it all back together. Now when I drive the car, it wont shift. It goes in reverse fine but 1,2,3,4 are all the same. I,m not sure what forward gear it's in when driving forward. Feels like second but not sure. What are some things I can look at? I did refill with fluid.

 

I scanned with datamaster and no codes came up for the trans. I hooked up datamaster and while in the garage with the brake on, went through all the gears. Datamaster reads that I am going to all the gears. Any ideas why it is not shifting properly in the forward gears?

 

Ever find out the problem? Mine is doing the same thing... although mine is definitely in first gear... just won't change out of it.

 

Not yet. I'm going to check the wiring when I get a chance.

 

The 6 speed or the auto ?

 

Auto. 6spd is gone.

Governer gear was stripped in the auto, which let me shift out of first, but then I found out the tranny was toast! Slipped into third and never would go to 4th.

 

Found it. The VSS was unplugged.

 

Sweet! Simple fix!
