I believe the seats are bolted to the floor of the van. Make sure you unplug all electrical connections before removing the seats.

did you check the fuses

Okay, there are a few engines that come in this van, lucky there the same except,they come with or without ac or airpump, so i will give you all of them and you choose the right one.

The fuses are located on a fuse block, they provide increased circuit protection and reliability. The fuse block is located under the left side of the instrument panel and steering column. The fuse block should be visible from underneath the steering column, near the pedal bracket. If the block is not visible, check for a removable compartment door or trim panel which may be used on later models to hide the block. On 1996-97 models, there is also a fuse/relay panel mounted underhood.



Fig. 1: If the fuse panel has a concealed cover, unscrew or unclip the retainer and remove the cover:



Fig. 2: Some fuse panel covers contain a fuse puller, spare fuses and a diagram of the fuse locations:

Good luck (remember rated this help).

1994 chevy 3/4 ton van, you have a 4L60E ?
You have to pull the trany pan, ther are 2 solenoids A and B. You will probably want to replace both, they are at the front on the valve block. www.rockauto.com

chilton and hayes both make a great book think you can get em at chapters indago

I just had the same problem. If it is a regular van try under the driver seat in a plastic box. If it is a conversion van try in a pannel just behind driver seat on side of van wall behind a pannel that looks like a vent.
