  • 20280 - B&M Deep Automatic Transmission Pans is rated 4.5 out of 5 by 2.
    Rated 4 out of 5 by from I bought the pan about 2 weeks ago. Everything was great except the cheap gasket that came with the pan and parts. Please upgrade the gasket to the level of the transmission pan and everything would have been great. Upgraded gasket complements the part for any classic car enthusiast.
