Shift with Confidence: GoPowertrain’s Remanufactured 8L90 & 10R80 Transmissions

In today’s high-performance trucks and SUVs, two names stand out in the transmission world — GM’s 8-speed 8L90 and Ford’s 10-speed 10R80. If you're dealing with slippage, overheating, or just plain failure, GoPowertrain has the drop-in solution you’ve been waiting for.

We stock thoroughly remanufactured 8L90 and 10R80 units — dyno-tested, updated, and ready to go. No gimmicks. No delays. Just top-tier driveline performance backed by real support.

The 8L90: Cooler By Design

Let’s talk about heat. The factory 8L90 transmission uses a thermal bypass valve that can restrict fluid flow when it’s most needed — especially under heavy load or towing.

That’s why every GoPowertrain 8L90 includes a bypass delete kit as standard. By eliminating the OE-style bypass, we allow the fluid to flow freely, keeping the transmission cooler, healthier, and more durable in the long run.

Pair that with our comprehensive reman process — fresh clutches, upgraded seals, vacuum-tested valve bodies, and thorough dyno validation — and you're getting a reman that's truly ready for battle.

10R80: Built Right. Backed Strong.

Ford’s 10R80 has become the go-to trans for the F-150, Expedition, Mustang, and more — but wear, contamination, and tuning stress can take a toll.

At GoPowertrain, every 10R80 is:

• Completely disassembled and cleaned

• Updated with new frictions, steels, bushings, and gaskets

• Vacuum and pressure tested

• Hot and cold dyno-tested to OE+ standards

While the bypass delete isn’t needed here, our process ensures every 10R80 we sell is tested and trusted before it ever leaves our facility.
