Transmission Oil Pan Gasket Fit for GM Turbo 350

Excellent product to stop the dreaded thm 350 fluid leaks

Good fit and good seal. I had to retorque the bolts a few times over several days to make certain that they stayred tight. I initially thought the gasket might be leaking, however after careful analysis, I determined that the source of the fluid was coming from the modulator and the shifter shaft seal. They were small leaks, but they would wick around the outside of the pan gasket making it appear that the pan gasket was weeping oil. Replacing the modulator valve and the shifter shaft seal solved the issues.

Made very good, extra thick, seams to have sealed very well.

This thing is worth its weight in gold! Clean your surfaces, pop this dude in and torque your bolts right! Hey, no more leaks!! That's never happened with anything else I've tried, and this is a first. So far, it's been good. I haven't had it under load yet bc I just broke in my flat tappet cam after engine rebuild. But I sent that engine to 2500 rmps for 25-30 min, surely I honestly expected it to leak, but not one drop. Worth it!

Great gasket. Just be aware that this gasket is not for a factory stamped steel pan with a ridge around the flat mating surface. I had to get slightly longer pan bolts because of the thickness of the gasket. But, it was worth to get a better seal.
