Verify exact spec on the dipstick label or owner's manual before fill. Recommended change interval: every 60,000 miles for normal driving, 30,000 miles under severe service (towing, stop-and-go, hot climates). Pan service typically takes 6 - 8 quarts; a full fluid exchange takes 10 - 14 quarts depending on cooler-line capacity.
SRV: 1 day. Rebuild: 3 - 4 days.
Fluid service and inspection complete the same day. Solenoid or sensor replacement: 1 day. Torque converter or seal repair: 2 - 3 days. Full rebuild with road test: 4 - 6 days. Time estimates assume parts in stock - call (312) 626-8759 to verify availability for your specific vehicle.
Every vehicle needs diagnosis before anyone can promise a repair path. These are the situations we help organize before you decide what to do next.
Tell us when it happens, whether reverse still works, and if warning lights are on. A scan and fluid check come before guessing at a rebuild.
Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.
A failed solenoid, valve body, converter, or internal clutch problem can lead to very different repair paths. The goal is a clear diagnosis and written estimate.
Yes - 8L90 TCC shudder is the most common Escalade complaint. Start with a Dexron HP fluid exchange. If shudder returns within 500 miles, converter replacement is the permanent fix.
More so than the 5.3L - higher torque accelerates SRV and TCC wear. More frequent fluid changes (every 30k) recommended.
No - early 10L90 production had harsh shift issues. Check for pending PCM updates. If mechanical, valve body service resolves it.
Escalades hold significant value - $40,000 - 80,000 used. A rebuilt transmission with 2-year / 24,000-mile warranty is absolutely the right call.
3 - 4 days.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
