AUTOTTEC 4L80E / 4L85E Transmission Oil Pan Gasket (Fiber) 1991+ Chevy GMC Hummer

Got a leaky transmission pan on your 4L80E or 4L85E?

This is the gasket you need.

It's a brand new, Pro-Grade Durapren fiber pan gasket from AUTOTTEC.

It's a direct replacement for a ton of GM applications from 1991 onwards, including Hummers, Chevys, and GMCs.

It replaces OEM numbers like 8677743 and interchange numbers like 34300E.

Just a quick heads-up: this will *not* work on a Jaguar, so don't grab this for that.

It's a high-quality, US-made gasket that'll seal up your trans pan tight.
