My 1996 GMC Yukon 4x4 transmission will only drive in 1st and 2nd
My 1996 GMC Yukon 4x4 transmission will only drive in 1 and 2 gear. When I put it in 3 or drive, the RPM shoot up and then have to drive in 2 gear.What do you think this is and how much to fix? Thanks

It will take off from a stop in overdrive but as soon as it shifts into 3rd at about 30 miles per hour it jumps into neutral? If yes, you have a burnt 3/4 clutch. The transmission will need rebulit. Cost of about 1600 dollars.

You can put the shifter in 2, 3, or overdrive. It will still start in first and shift up to whatever gear you have selected. Try it, you wont damage anythingl
It winds up in 1st and then shifts right from 1st into 3rd. Then never shifts into 4th. Plus rev is gone. You broke the sun shell. The transmission will need to rebuilt or replaced.
this sounds like the pressure valve is going bad on third gear. cheap fix try Lucus transmission additive to increase the pressure. To do it right go to a good transmission shop an have it serviced and flushed.
I don't think its plug wires. When you say it won't shift into 1st? It takes off in 2nd? Does it shift to 3rd and 4th? Or is it a shifter problem? Like it won't go into manual 1st
It is an internal trans problem. I build transmissions for a GM dealer. It is going to be the input carrier, forward sprag, and 3rd/4th clutches. I have seen several. Get it to your dealer. That truck has a 100,000 mile powertrain warranty. That includes the trans. Good Luck.
the teeth and bearings on the 2nd gear and 2nd gear shaft are worn, when putting it into 4x4 it puts a heavier load on the shaft that quiets the bearings and forces the gears tighter together.
