Questions & Answers Ask a Product Question

I have a 1967 c10 with a th400 attached to a 355 and a aftermarket radiator. I don't really want to mess with the steel lines and bend them correctly. Will this work for me correctly?

Asked by LAIN on January 18, 2018


Yes I believe they will. They are used on my truck to connect a cooler to my transmission in the way you described.

Where can I find these 5/16 to 6AN fittings for the transmission.? I have a 700r4 but I bought an aftermarket radiator that has 1/2-20 invert flare for the tranny cooler.. I would like to build lines to fit this application.

Answer This Question


Do the transmission side fittings screw directly into case, or is factory flare fitting still used between these and case?

Asked by JEREMY on May 16, 2018


Thanks for the question. You must reuse the factory flare fittings.

Will this work on a 47re?

Asked by KALEB on September 21, 2017


Thank you for your question. Advance Adapters 21-1501 are specifically designed for use on the TH350, TH400 & 700R4. The lines may not be large enough for your particular application and would require additional adapters fittings not supplied in the kit.
