I have a 1993 Chevy Suburban im having problems with the transmission. When i bought the truck it drove fine but after awhile it started not going into Over Drive, then it got to where it only stayed in 2nd gear so i took the transmission out and rebuilt it completely. New clutches, clinoids, pressure censers, shift kit, and updated wiring harness inside and outside the transmission. I put the transmission back in the truck and its shifting hard and still not going into Over Drive. Can anyone tell me what is wrong with it. The truck has the 454 with 4l80e transmission.

 

Does it have a towing package?

 

Yes it does have a towing package. I forgot to put that on the post.
