Title: 69 GT350 transmission fluid
Post by: SChatman on September 03, 2018, 01:21:32 PM
Recommended Transmission fluid, my car hasnít been running since the days of Type F. Iíve heard several opinions suggesting Mercon synthetic and people say no Type F.
Thoughts?

My local NAPA shows to still have Type-F on the shelf.  I had my C-4 rebuilt about 4 years back.  I asked the rebuilder and they said to use the Type-F or Mercon would also be fine.  I used Type-F from NAPA (Think it was Valvoline)

Iíve found type F at the auto parts stores but the Transmission guys are saying the Mercon V is better and NPD sells Motorcraft Type F and Mercon V and charges more for the F. I havenít heard any reasons why one over the other yet, youíd think that rebuilders would be able say why. 
 Thanks for your reply

Up to you then.  I got to trying to recall my old memory tapes.  I think my tranny guys said the same as yours are!  I might have filled it with Mercon! I'd have to dig to see if I kept a receipt for the fluid.  I know I kept the rebuild receipt.  Anyway, if the tranny guys are saying Mercon V if good then go with it.  They should know the rebuild kit they used would be OK with either fluid.

My local Walmart has type F for $2 something a quart.  The auto parts stores charge $5-7.

  Is that the generic stuff?  Yeah, I've used it also.  Got a few quarts of it out in the shop.

The best type F is the synthetic version of B&M Trick Shift

the 2nd best is the conventional B&M Trick Shift

 
These products are NOT additives, but a stand alone type F fluid.

PS.   The above reccomendations are applicable to the fluid choise in the vintage ball drive Paxton supercharger..  my last Paxton had 75,000 + miles on it with ZERO maintenance other than changing the  synthetic B&M fluid fluid at every oil change. Numerous high speed endurance runs on the course of the Big Bend Open Road Race, 53 miles each way @ maximum rpm 95% of the time.  A fluid cooler was also installed.  If you have a Paxton this is the way to keep it from wearing out. At the time I sold the Paxton, I sent it to Craig C to have it checked out. He reported it had no wear and needed nothing.

Thanks everyone fo the suggestions. Iím being told by the transmission experts that Iíve since talked to That say the Mercon V is better then Type F because itís updated with better additives and the synthetic is even better. Thanks again.
