I removed the transmission in my 99 Silverado to have it rebuilt. (It only took me about 17 hours, on my back in my driveway. Why I decided to do it myself is beyond me!) "While I was in there" I decided to address the several leaks...one of them being the rear main seal.I bought this kit and installed it. I also installed a new dogbone, a new oil cooler bypass gasket, and a new oil pan gasket.I finally got my transmission back from the guy who rebuilt it, and had to recruit a friend to help me get the transmission back in place. So after spending another 15 hours installing the transmission, transfer case, drivelines, electrical connections, exhaust, and filling everything with fluid, I started it up and went for a test drive; about 10 minutes around the neighborhood.I parked back in my driveway and looked underneath: oil is POURING out from the bottom of the bellhousing. Grrr!!!So I had to remove my transmission AGAIN to see if this kit was leaking. I was out of time and had to hire somebody to help me; to the tune of $450. Sure enough...the circular seal was leaking. We replaced it with an OEM GM kit, put it all back together (another 15 hours on my back), and now: no leaks.Bottom line: don't trust this kit. :-( I'm returning it for a refund, but of course I threw away the box weeks ago, but they'd better refund me anyway.

Highly recommend this route of changing the cover and gasket in one piece Vs over just seal

Worked for about 3 minutes before started leaking from the rear main seal. Plate to engine gasket seems to seal fine but the rear main seal did not do its job. Should have gone with a reputable gasket manufacturer. Not a fun job to have to do again right after completion.

This product was economically perfect. I installed it on my personal vehicle in about 5 minutes after clean up. Would purchase again if needed. Update: it started leaking again. Sucks now I have to pull out trans and transfer case AGAIN.
