A leak free 727??

A leak free 727?? - 10/15/16 12:37 PM

My 64 has a puddle of tranny fluid under it. It appears to be weeping around some of the bolts. I also hope the front pump seal isn't out. I am thinking that I should have the pan gasket changed and maybe put a new deep pan on it. So what is everyone using for a pan? I see Trick Flow has one at a good price. Thanks! Ted wave

Whatever you use, DO NOT use a chrome pan. I have seen more chrome transmission and oil pans leak on all kinds of cars, than anything else.

I'm using the Mopar Performance deep pan with Fel-Pro TOS18583 gasket.

I have an finned aluminium deep pan and use a re-useable pan gasket, no leaks whatsoever. Can't remember the manufacturers but Todd Marsh got them for me. HTH's

bone yard.... well ok, a core went back with no pan smile 46RE stock pan, mopar reusable gasket. torqued to 125 inlb... been on/off several times over the years for service and no leaks. Another godsend was using a dipstick tube with the "GM" style seal (mopar adopted that on later truck models).

Finned aluminum works well. So does the factory (or aftermarket copy) of the 518 pan. My 518 replacement is still using the same reusable gasket after many inspections. Many times the cables leak at the crimps. I have the fix. Plugging the front vent and relocating helps the bell housing leaks. The park cable adapter is often warped. It can be stoned flat.

The cables can be repaired with heat shrink for wiring. Use the type with the glue. I have it if you need it.

where have you found the best source for the marine grade heat shrink ? i am ready to re-stock my selection of sizes and colors, and would prefer to get 2 or 4ft sections if possible.

Can't say on the capacity... the 47/48RE pans are slightly deeper than the MP deep pans they had.

In the early 90's we cut the end off our 727 dipstick tube and brazed on a chevy end and used their seal. Worked great! Mopar went to a similar style in the late 90's on their trucks and it, unlike that stupid oring, didn't leak either.

....just like this:

The locking dipstick/tube I bought from Cope has the gm style rubber seal on it. I'm using the late pan on my 727, IIRC it came with the filter spacer from Mancini.

People beat up the tube, by working it back and forth, as opposed to pulling straight up, and slightly turning to break the o-ring loose.
