Post subject:  ATF Leak

The TorquFlite in my '64 Valiant has developed a leak in an area I've never seen before. The shifter cable jacket wore through from riding against the exhaust pipe. The hole is about 1/8" in diameter, and apparently there is enough internal fluid pressure to force it out the hole..

I really don't have a good idea how to repair it, and I don't want to replace it unless absoluetly required, so I'm hoping someone has an idea.

The only thing I can think of is to thoroughly clean the fluid off, solvent clean, coat the area with ATF resistant gasket sealer, and then wrap it with something that will survive the exhaust pipe heat and will hold the sealer tight enough to keep the hole plugged. I'm thinking a small screw clamp over a piece of sheetmetal or split tubing, but I'm concerned it might be so tight that it would make the cable bind.

Has anyone successfully repaired such damage?

Get a piece of shrink tubing with sealer, from an electrical supply house. Remove the cable, and slide the tubing over the "clean" cable. Heat with a heat gun. Reinstall cable.

It's not a pressure leak; there is no pressurized fluid inside the cable. It's just a regular slosh-type leak. Charlie's method works, but mine is easier because you needn't remove (and replace, and adjust) the cable.

Being unwilling to remove the cable unless absolutely necessary, I opted for Dan's method. Unfortunately, they no longer make the Mopar sealer, but I used a similar product.

It's not leaking as it sits in the garage, but after it cures overnight, I'll drive it and see if it holds up.

Yeah, they do. I just bought some about 12 days ago, and it's not going to be discontinued any time in the foreseeable future. You ran up against a lazy dealer parts counterman or something.

My counter guy said that his mechanics were upset that Mopar quit carrying their great sealer, but that it happened over a year ago. They now offer a very expensive red product that I bought a few months ago, but don't care for. It's too thin and messy.

My son is a mechanic in an independent garage in WA, and he said he can't get it at the Enumclaw dealer either, so he switched to The Right Stuff, made by Permatex. That's what I used for this job. It's black and sticky, but doesn't have the body and excellent adhesive characteristics the Mopar product had.

Perhaps your dealer had a large supply on hand...or perhaps Mopar recently began making it again. I hope it's the latter.

I'm still havin' a problem buying this notion. I've bought too many tubes of the Mopar black and grey RTVs, from too many dealers throughout North America, over the last 12 months for your guy's story to make sense.

I had no reason to question what I was told at the time, especially when it came from two sources. However, both are small dealerships, so the next time I'm in the city I'll check the big guy's parts department.
