Mar 18, 2011 - The 4L60-E is an automatic shift, four-speed overdrive, longitudinally...... 4l60e 2002 gmc 4x4 was not driven for 1 year,will not shift into 3rd or ... I have a 2005 GMC envoy 4x4 6 Cylinder I assume it is a 460LE Transmission.

Ok if you have 1st and second gear and it shifts to neutral instaed of 3rd , that means the 3-4 clutches are burned up.This is common problem with the 4L60E transmission and the transmissionwill need to be removed and rebuilt ot repaired.The 3-4 clutches are the weak point in the trans and i usually use a z-pack when rebuilding them.It increases hold capacity and durability.

If you lost reverse and second gears,the reverse reaction shell splines have stripped out.This is a common problem on the 4l60e trans.A aftermarket heavy duty unit is available and highly recomended.

sounds like the clutch packs are worn out or not enough oil pressure engaging the first gear clutch pack.

sounds like you got a bad shift syncro for 3rd gear, its inside the trans,cuse ive never adjust shift cables on a s-series now matter what was done to the trans,and that cable controls more than just 3rd gear so its gotta be the syncro,,sorry,,,cheaper to get a used trans than to fix

input shaft in gearbox has failed

Sounds like a speedo gear in the transmission ... I think the tahoe one had a speedo cable the speed sensor is located in the speedo ... will cause all those to fail if speedo is not working as did in my Astrovan

It just holds 2nd forever. Is the 1-2 shift point high?

this is known as "limp mode"

there should be a fuse in the dashboard fuse panel, or possibly the one under the hood.. one will be labeled trans or tcm - something of the like...test ALL fuses in the fuse boxes for good measure, and change the fuses if you find any blown.

ALSO....

Did you recently have a remote start system installed? If so, they need to hook up the smaller white wire in the ignition harness to turn on with the ignition power from the remote start unit. If the ignition wire and the white wire (transmission control) are not powered at the same time, the trans will go into limp mode.
