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.
Valve body: 1 - 2 days. 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.
The ZF 8HP is an excellent transmission - same unit used in BMW. When maintained with ZF Lifeguard 8 fluid, very reliable.
Likely the ZF 8HP valve body solenoids. Common on units with original or extended-interval fluid. Diagnostic first.
Typically 3 - 4 days vs. 5 - 10 days at a Chrysler dealer, and our pricing is 35 - 50% less.
All 2015+ Charger models - SXT, R/T, Scat Pack, Hellcat. Same transmission family, different torque ratings.
The Hellcat uses an 8HP90 - the high-torque version of the ZF 8HP family. Rebuild is similar but the unit is larger.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
