Question about 1990 Chevrolet K1500
Just rebuilt the 700R4 in a Chevy Silverado. I have Reverse, OD Slips Badly, Third, Second and First seems to drag but works. No noises or grinding.
I suspect that the oil pump is not producing sufficient pressure to do the job. have a pressure test done to check this. It is possible when reassembling the unit that there is a leak in the system (missing-damaged seals ,gaskets ) that is allowing oil to squirt of a join (loose bolts). Recheck the band and clutch pack adjustment now that it has been run.

this problem is a common failure associated with your shift solenoinds inside your tranny. of course a shop is not gonna tell you this because by the time you wanna get it repaired it is usually too late and have already cause damage to your clutch pack and internal parts, thats the main reason why a shop wont mess with just replacing your shift solenoid (aka valve bodie)

check color and smell of trans fluid, if not bright red and had a pugnant odor then the trans needs to come out and torn down, You can try a fuel filter that can cause a driveability problem

There are to many things that can cause this problem, best thing to is go get the ECM scanned for DTC codes at a transmission shop or Auto zone or Parts Source since they scan for free.
The ECM should have DTC code in it's memory on how the transmission is Performing and have the Transmission line tested for Fluid pressure.
Good luck and hope this helps. Oh and also ways check with more then on transmission shop if there tell you that you need a new Transmission,
It could be a simple as the transmission filter falling off causing the lost of transmission fluid pressure. Check the transmission fluid too.

Is there anyway you can pull a code? Because it can be solenoid related,for this type of transmission the speed sensor (VSS) is prone to do this,also how is the transmission fluid is it brownish or dark dark burnt , because if it is its a mechanical failure.I can pull a code if in T.O
