problem with a 4l60e transmission

[silverado1992]

Hello I have a 1996 Silverado and it will not shift out of first gear. I have had the pickup for about 6 months and when I got it, it would shift if I accelerated to about 30 and let off but then I went though some mud and got stuck,i kept shifting from reverse to forward and I got out of the mud and it would not come out of first but reverse works fine and it will not shift manually at all the pickup has a 4l60e transmission. Does anybody have suggestions of what I should do

you need to have the transmission checked out and have about 1500.00 to pay for what is IMO a transmission re-build. after the repair replace the fluid and filter around 10,000 miles. or sooner if the fluid is off colored.

make sure they use the new now approved GM dexronVI fluid.

DEXRON III IS A NON APPROVED GM FLUID SERVICE CHANGE 2006.

What do you think it's wrong with the transmission and could it just be a shift solenoid

Are you sure it is 1st not second, if it is second, this is limp mode and yes it could be a solenoid, I would start off with a full scan at a trans shop to see there are any pending codes and they can command upshifts to see what is what.

Well it will shift if I go around 30 and let off but even if I barely touch the throttle it will downshift back into first

When you get stuck and rip it forward and back wards.
It will usually break center sprag or case.
