Had to do a transmission in my truck, rear main was leaking so bought this to fix it, worked as it should, no more leaks, it’s Dorman, cheaper then local part store,

03 silversdo perfect fit perfect no leaks. I also done my 88 f150 same deal. This part either was for the 88 or the 03 both out performed.

Perfect. Same exact part at autozone and half the price.

Worked perfect 2012 Silverado 4.8 4x4 The bolts it came with were to short. Just cleaned the original ones up and worked perfectly. No leaks so far

Worked great I pulled the dorman seal out and bought an ac delco seal for my own piece of mind used alignment tool to install straight silicone underneath and in the corners and done

Product comes with the seal installed. Careful installation allows it to work properly. With the crankshaft cleaned very well, no rust or sharp edges you slip the new seal in place dry and clean. No Oil or grease because this is a teflon seal. Once fully in place by hand start all the upper bolts and then install the lower pan two long bolts leaving all bolts loose. Slowly tighten the upper bolts working around the seal area first, letting the seal be put in place centered on the crankshaft so you get long life. Now torque the upper bolts first and finish by tightening the lower bolts and torqueing them. You read of lots of guys saying this does not work and leaks. They installed it wrong in most cases. IF you tighten the lower 2 long bolts first the seal will egg shape on the crankshaft and leak. If you don't tighten the upper bolts slowly working your way around the seal and gradually bringing the entire plate tight against the block you will cause issues and maybe even break the new plate. Follow procedure and it works.

Great quality, fast shipping
