4L 60E - 2001 k1500 will not shift into 3-4. Oil is not burn't and stifts great into1-2

It sounds like you shift solenoids need to be replaced in your tranny.

If it indicates on the dash as being in D, but you never feel it shift out of 3, the problem could be as simple as checking your transmission fluid level and top off as needed or a bent linkage that prevents the transmission from engaging D. Try setting the shifter between N and D and see if it shifts up out of 3 to D. If that works, the linkage between the shifter in the cabin has been loosened or bent. This should be a relatively easy fix for your mechanic.

If when checking the transmission fluid level, it is found to be brown or smells burnt; it may indicate a larger, more expensive repair. Transmission fluid should be pinkish / red in color and smell like hydraulic fluid or oil.

my Chevy C2500 has an electronic actuator / solenoid in the front differential they burn out frequently. They electronically lock up front differential. I bought a manual actuator from a 4X4 shop for $250.00 no more problem and no worry that if I had bought another electronically operated one it might burn out way back in the outback

go to the scrapyard and find a accident damaged vehicle then buy the box and the computer and change the whole lot ,failing which buy a newer secondhand car as it may be cheaper in the long run preffably one with a manual gearbox

Raise the vehicle and soak the transfer case shift linkage with penetrating oil.After it sits a while you may be able to limber it up by working it back and forth.Common symptom from lack of regular use of shifter

two problems with these trucks the push buttons there self and the encoder on the transfer case.

Hello. yes, you are burning oil resulting in the white smoke. Try a heavier weight oil in the crank case, or an oil additive specifically for high mileage, oil burning vehicles. There are a number of them on the shelves at any auto parts store. J.

Sorry it will not work, the internals are the same but the transmission housing has changed. The key distinction of the Later 4L60-E (1997-2006) from the Early 4L60-E (1992-1997) or 4L60 (1990-1992) or 700R4 (1982-1989) is the six-bolt "hex" rear output or tail-housing / adapter pattern. The previous versions featured a four-bolt square bolt pattern at the adapter or tail-housing. Additionally, the removable bell-housing is also another distinguishing feature.

Two-wheel-drive versions have tail-housings and typically a longer output shafts than four-wheel-drive versions, which have various adapter assemblies and a shorter output shaft.

try adjusting kickdown cable to manfactures spec this may work

It should tell you on the Shifter whether or not that you can Shift on the Fly. Check the Manual first if there is one in the Truck. Some Models had this and some Did not. Was an Extra from Factory Option.
