48RE: full rebuild with updated governor solenoid and overdrive drum. 68RFE: solenoid pack replacement if clutches are intact; full rebuild if OD clutches are burned. For tuned trucks: heavy-duty OD clutch pack upgrade is essential. Billet builds available for high-performance Cummins applications.
48RE/68RFE/AS69RC: ATF+4 - change every 20,000 miles for towing
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.
Standard rebuild: 3 - 5 days. Performance build: 5 - 7 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.
It's common - especially on tuned trucks. The stock 68RFE OD clutch pack is undersized for Cummins torque when modified.
If you tow heavy or have any Cummins tune, yes - absolutely. We offer heavy-duty OD clutch packs and billet components.
The AS69RC is an Aisin-built alternative - significantly more robust than the 68RFE. If your Ram has it, you're better off.
3 - 5 days for a standard rebuild.
