Question about 2003 Cadillac Escalade Ext
Left the house this morning with everything working fine. a few miles down the highway it jumped out of overdrive and would not go back in. once in town, from a stop, it would reach about 5,000 rpms before shifting.
Run the fault codes before you tear into the tranny as the recorded fault will pinpoint exactly what you have to fix. Most likely a faulty TCM or a od servo/solenoid.

SOURCE: Transmission problems
First off, I'd try changing the fluid and filter in the transmission. I know a lot of cars claim "lifetime fluid" - it's BS. Believe me, even the lifetime fluids get very dirty. Change out the fluid and filter, and you could even add some Lucas stabilizer to it - that may well help cure the problems.
When the transmission goes completely, it may lock up the drive wheels, sending you into a careening slide, or it may kick out to neutral and coast to a stop. It's also possible that if it flat-out blows, it could fragment inside and you'd hear what sounds like bolts in a blender as you coast to a standstill.
Discounting the transmission blowing up, and just looking at driving in a drive gear other than overdrive, you're looking at more heat in the transmission due to the higher gear RPM, shorter fluid life, possible slippage of the bands down the road due to heat, and of course decreased gas mileage due to the engine running at higher RPM.

Sounds like a solenoid or two in the transmission is dirty or defective. Needs a transmission rebuild to rectify it, or a replacement transmission that has lower miles or a newer transmission that doesn't have this problem.
One can try a transmission flush and refill, which costs about $100 or so, but that may not fix the problem. A rebuild is much more expensive, but is the way to go if you plan on keeping the vehicle for years to come.
