Help! Transmission trouble...
Just bought a '92 c1500 5.7 L with 700r4 tranny, the truck sat for 10 months before i bought it and it doesn't want to shift out of 1st until it gets good and warm after about 20 minutes or so. I am going to swap tranny's next week if I can't figure something out. Thanks1992 Chevy C1500 Ext. Cab Longbed

First thing you want to do is release the TV cable from the throttle body. Start the truck and make sure it's in park with the E brake on.
Next use your left hand or have someone raise the engine RPM to about 2000 RPM. Now with the engine screaming at 2K pull the TV cable out all the way and then back in. In and out in and out as fast as your wrist can repeat this action. Do it at least 25-30 times in a row while the engine is running @ 2000RPMs.
This little trick works most of the time on 700R4 transmissions if the TV valve is stick in the valve body.
Try this when the engine is cold and it's acting up. Let us know if this works!Jim

You will probably need a new flex plate if you have a vibration.

Make sure you get a second opinion before you buy a transmission. Good Luck!
