Car Forum / Chrysler Cars / July 2007Transmission Pan Removal
Is it better to use the gasket that comes with the after market transmission filter kit ,or use Black RTV on the transmission pan after replacing the filter? > Is it better to use the gasket that comes with the after market transmission > filter kit ,or use Black RTV on the transmission pan after replacing the > filter? There's a third option: Have the dealer order the metal sandwich gasket. Very reliable, re-usable (up to 3 times - the life of the vehicle for most people), no problems separating pan the next drop, no risk of reaction of ATF with uncured RTV, and, in general, less dependent on the skills and attention to detail of the installer. The choice is yours. All three will work fine. RTV is the least desireable in most people's opinion for the reasons stated. Bill Putney (To reply by e-mail, replace the last letter of the alphabet in my address with the letter 'x') I second Bill's recommendation. The metal/silicone gasket has served me well on three different Chrysler vehicles.

Post back with vehicle information (make - model - year) if you need the gasket part number. Many dealer parts guys/gals do not know these gaskets exist, but the part numbers for the various Chrysler transmissions are given in a TSB that many of us have access to. Won't take but a minute to look it up. Or if your parts guy is ignorant of this part, tell him there is a TSB with the part numbers in it - he should be able to search the TSB's. Oh - what the hey - tell him it's TSB No. 21-05-99 Rev. A - "A/T Pan Gasket - Reusable Design/Installation". Bill Putney (To reply by e-mail, replace the last letter of the alphabet in my address with the letter 'x') One other thing to add is to NOT use the aftermarket filter either. Take it from someone who had one disintegrate and grenade a trans > Is it better to use the gasket that comes with the after market > transmission > filter kit ,or use Black RTV on the transmission pan after replacing the > filter? > Is it better to use the gasket that comes with the after market > transmission > filter kit ,or use Black RTV on the transmission pan after replacing the > filter? I never have any trouble at all using RTV. The key is to leave it overnight before you fill it up. >>Is it better to use the gasket that comes with the after market >>transmission [quoted text clipped - 3 lines] > I never have any trouble at all using RTV.

I've switched to using Permatex "the right stuff" on all my transmission pans from 727s and 904s to the 42LE. You can put it on, wait 10 minutes, and then fill the pan and it will still cure correctly. No problems at all for 6-7 years now, and its not particularly hard to open back up if you know the tricks (drive a putty knife through it in a couple of places, and then tap a pan corner while gently prying downward. I plan to try the metal sandwich gasket on at least one of the cars, but I will NEVER use a composition gasket of any sort (fiber, cork/rubber, whatever) on a transmission pan again. careful some of the newer pan gaskets are reusable and intended to be > Is it better to use the gasket that comes with the after market transmission > filter kit ,or use Black RTV on the transmission pan after replacing the [quoted text clipped - 3 lines] > Message posted via CarKB.com > http://www.carkb.com/Uwe/Forums.aspx/chrysler/200707/1 What's wrong with using genuine GE 100% Silicone Bathtub and Window Caulk. The stuff is dirt cheap, comes in large economy size tubes you use in a caulking gun, and is available at any Walmart store, in the paint department. That's all I use on cars and it serves me well, never having a leak. The trick is to make a paper gasket, using the old gasket as a pattern. The best paper is an old shoe box or other light weight cardboard. Apply a light coat of GE 100% to both sides of the paper gasket, then also to both metal surfaces to which the paper gasket will mate to. You want to wet the surfaces with GE 100% to effect a quality job. Then just bolt it together and forget about leaks. |
