Transmission Line Question

1982 Corvette
350 CID
TCI 371000 Transmission

I had to cut my transmission lines that were on my old 700R4, and I was wondering if I could put rubber from the tranny to the original steel lines. I did not want to have to replace the entire line if I did not have to. I found some brake line, but the tubing hole is slightly smaller in diameter than the original. Any advice on this would appreciated.

TIA,
CDM

A piece of fuel line will work without any problems.

While there is ATF line I know from expierience that you can use fuel line. Now this is personal expierience maybe everyone's situation is different, what makes you say the fuel line won't work? Don't take me wrong I'm not trying to be argumentitive but if there is something I can learn then good, but for the last 20 years or so if I had to splice a piece of trans line I have always used fuel line with no trouble.

I'm just passing on what I was told at a good parts store. Both ATF and fuel line have the same level of solvent resistance. The difference is that the ATF line also is heat resistant.

Thanks for the advice. I will get the hose and not concern myself with getting the steel tubing.

I've not heard anything about it, but it looks like a good system. Basically hard line to about where it connects to the radiator, then braided steel.

If you use rubber line, make sure it's the FUEL INJECTION kind. It's rated for 100+ psi, where the cheapo stuff might actually blow under tranny pump pressure.

I've got about 8 feet of this in my 79 (from trans all the way to my tranny cooler and back) and haven't had any problems in 3+ years.
