  • Easy installation
This product was economically perfect. I installed it on my personal vehicle in about 5 minutes after clean up. Would purchase again if needed

  • Junk - don't buy
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. ... show more

  • Right part. Fit exactly

  • Good fit - great price
This was not the most expensive part available but worked really well. You have to be careful positioning the cover gasket as it has a bit of spring to it. Also lube the sealing surface of the crank and carefully press the seal onto the back of the crank as you push out the preinstalled white plastic ring. The oil seal has a tendency to roll a bit at the edge as you slide it on. (mine did) It caused a small leak for about a week till it worked itself out - no leaks at all now. ... show more

  • DON'T BUY. ABSOLUTE TRASH!
This gasket kit is trash. I paid to replace my transmission, picked up and drove 15 miles home. Leaking all over the driveway. Took it back to transmission shop. The gasket failed. Read other reviews! Chinese junk! 40 dollar gasket cost me 1000 in labor!
