New member/ Tranny question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

jeffbo · 12-03-2002, 12:26 AM

I'm new to the board and just wanted to say hi to everyone. I've been reading the message boards for months and finally decided to register. My project currently is my '72 C-10 LWB. I've bought the truck when I was 16 (I'm 19 now) and have just recently been getting serious about restoring it. Just pulled the tranny a few days ago to get it rebuilt ( the 2nd time since I've owned it) and plan to start on the engine soon, building it as time and $ allows. I also picked up a '68 C-10 about a month ago for $200. It's complete and in pretty good shape, but there's no title for it.
I do have an interesting question. Took my tranny to a local gearhead to have him rebuild it. We got to talking and he said that he uses Type F fluid in all his TH-350s. He says it's better than the GM Mercon fluid. I'd never heard that before, but this guy has been building trannys for 20 years so he must know what he's talking about. Has anyone else ever heard of doing this, or done this themselves?

P.S. Any other members from South Dakota?

I don't know the answer to your question but welcome from the other Dakota! There are quite a few here from SD.

I have heard of it...but very few ppl do that any more.
I think that is just an old school opinion. I ahve only heard old timers say it, and the new dextron is used in fords too now.
Dodge is the odd ball now with special tranny fluid.

I used to use type F in my tranny's. Type f was supposed to not allow the clutches to slip as easily as dextron. I started using it because that is what B&M recommended using with their shift kits.

Welcome to the board!
I would say as long as he will warranty the tranny, for say 6k mi., put in what he recommends. However, I just had my tranny rebuilt and the shop said I should only use Mercon.

It doesn't matter much anymore since the new stuff is Dex/mec. I used the Valvoline and it covers both.
