According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 2002 Cadillac Escalade has 2 documented known issues, with 1 rated critical. The most serious is 4L60E/4L65E 3-4 Clutch Pack Burnup Causes Loss of Third and Fourth Gear ($2,200-$3,500 repair). Across all issues with published estimates, repair costs range from $250 to $3,500.

On the 2002-2006 Cadillac Escalade, gMT800-era Escalades use the 4L60E/4L65E four-speed behind the 6.0L LQ9/LQ4, and in a 5,800-pound SUV the 3-4 clutch pack is the component that gives out. The 3-4 clutch apply circuit runs through a small feed and the waved snap ring and clutch plates cook under sustained load - towing, hills, or just the vehicle's weight over time. It usually starts as a flare or slip on the 2-3 shift, then the transmission stops making 3rd and 4th entirely and drives only in 1st and 2nd (or goes to limp with no movement at all). The sun shell ('Beast' shell) splintering is the other classic failure and produces loss of reverse and 2nd/4th. CarComplaints lists 'Transmission Failure' as the #1 problem on both the 2005 Escalade (avg $2,800 at 79,000 mi) and the 2006 Escalade (avg $2,800 at 77,000 mi), which is early-life failure for a truck transmission. This is a separate failure from the later 8L90 and 10-speed shift-quality complaints.
RPM flares on the 2-3 upshift without the vehicle accelerating
Transmission stops shifting into 3rd and 4th, drives only in low gears
Loss of reverse along with 2nd and 4th gear
Burnt-smelling dark transmission fluid and clutch debris on the pan magnet
Harsh or delayed engagement into Drive or Reverse
How to Fix
Confirm with a scan and a pressure test before pulling anything. P0741 with a slipping torque converter lockup can be a solenoid or converter and does not require a rebuild; P1870 (transmission component slipping) on a 4L60E is the classic signature of the 3-4 clutch and worn valve body bores and does mean internal damage. Check fluid condition - burnt smell and black-brown fluid with clutch material on the pan magnet confirm the clutch pack is gone. Do not do a flush on a slipping unit; it will not save it and can finish it off. The correct repair is a full rebuild with upgraded internals: a 5-pinion or beast-style sun shell, an upgraded 3-4 clutch pack with additional frictions, a hardened input shaft, and a corrected valve body/servo. A rebuild that only replaces the burnt clutches with stock parts will fail again on the same schedule. Budget roughly $2,200-$3,500 for a quality rebuild or a reman unit installed. Adding an auxiliary transmission cooler is worthwhile on any Escalade that tows.
On the 2002-2006 Cadillac Escalade, gMT800 Escalades develop a rising-and-falling whine from the front of the engine that tracks steering-wheel movement and gets worse at low speed and full lock. The cause is usually a combination of the power steering pump's internal wear and aeration from a leak that lets air into the suction side - the pump then cavitates, which accelerates its own wear and eventually seizes the vanes. The two leak points are the high-pressure line's crimped hose end at the pump, which weeps under pressure, and the pump shaft seal itself. Owners frequently top the reservoir off for a year without finding the leak because the fluid blows back onto the crossmember and burns off against the exhaust. CarComplaints lists 'Front End Whining' as the #1 problem on the 2003 Escalade (avg $1,400 at 80,000 mi) and 'Leaked Power Steering Fluid' as the #2 problem (avg $500 at 115,000 mi) - the same underlying system reported two ways.
Common Symptoms
Whining or moaning from the front of the engine that rises when turning
Noise loudest at low speed, parking maneuvers, and full lock
Power steering fluid level dropping with no obvious puddle
Foamy or discolored fluid in the power steering reservoir
Steering effort increases or feels notchy when cold
How to Fix
Start with the cheap check: with the engine off, look at the reservoir level and fluid condition. Foamy or milky fluid means air is being drawn in, which points at the suction hose clamp or the reservoir O-ring, not the pump. Clean the area, run the engine, and turn lock to lock while a helper watches the high-pressure line fitting at the pump and the pump nose. If the fluid is clean and full and the pump still whines under load, the pump is worn and should be replaced - remanufactured pumps run about $80-$180 and a shop charges roughly $250-$450 installed. Replace the high-pressure line at the same time if it shows any weeping, since the labor overlaps. Always use GM-spec power steering fluid, not ATF, and bleed the system properly: with the front wheels off the ground, turn lock to lock 15-20 times with the engine off before starting it, or trapped air will make a brand-new pump whine. Ignoring it risks pump seizure and a shredded serpentine belt.
