Transmission ATF RTV Question
I am trying to buy Mopar ATF RTV 5010884AA for my transmission pans. Dealer says it's no longer made. He's trying to substitute an RTV that is not labeled ATF RTV, only labeled RTV. Am I getting the correct information?

Two months ago I purchased Mopar silicone RTV MS-GF-41-B (formerly known as ATF RTV) the Mopar part number was 5010884AD, a three ounce tube cost $7.70. The tube did not say ATF but it appears to be the same stuff.
If you use the Mopar RTV, follow these instruction from the service manual:
Also from the service manual:
If you use the Mopar RTV, follow these instruction from the service manual:
Mopar ATF RTV gasket material should be applied in a continuous bead approximately 3 mm (0.120 in.) in diameter. All mounting holes must be circled. For corner sealing, a 3.17 or 6.35 mm (1/8 or 1/4 in.) drop is placed in the center of the gasket contact area. Uncured sealant may be removed with a shop towel. Components should be torqued in place while the sealant is still wet to the touch (within 10 minutes). The usage of a locating dowel is recommended during assembly to prevent smearing material off the location.
MOPAR ATF RTV is a specifically designed black silicone rubber RTV that retains adhesion and sealing properties to seal components exposed to automatic transmission fluid, engine coolants, and moisture. This material is available in three ounce tubes and has a shelf life of one year. After one year this material will not properly cure. Always inspect the package for the expiration date before use.

I would contact Mopar with that new part number to verify it will work. I wouldn't want my pan to start leaking. Also, Mopar support can tell you if they have a new part number that supersedes that old number.

I've RTVd tranny pans 5 or 6 times always using whatever high temp RTV was available at Kmart, WalMart or local parts stores. Didn't make any difference they all worked just fine. Don't sweat it. Install the pan and wait an hour then fill it.
