"Needed a transmission for my F-150. Nationwide verified the exact match by VIN, and it showed up at my mechanic's shop palletized and ready to drop in. Saved over $2,500 vs the dealer."

Common Hummer Transmission Issues
These are the most frequent reasons Hummer owners need a replacement transmission.
4L60-E (H3) — Sunshell & 3-4 Clutch Failure: The 4L60-E in the H3 develops sunshell failure under the stress of the heavy vehicle and larger tires, causing loss of forward gears. The 3-4 clutch pack also burns from sustained 4WD use. A replacement is the only fix for sunshell failure — it cannot be repaired in-vehicle.
6L80 (H2) — Valve Body Wear: Same as other GM 6L80 applications — valve body bore wear at higher mileages. Deep GM inventory pool ensures fast sourcing — a replacement with fresh valve body internals is the reliable fix.
