ricci32:
what type of trans fluid do you guys use.
dreracecar:
The kind my tranny builder sells that way when the tranny goes south he cant blame it on me for using the wrong fluid.
By the way Mikes Transmission PG and his fluid
GlennLever:

Dolmetsch:
I use mobil 1 . Stable to 1600F and aluminum melts at 1250 to 1300 so I know it will never be an issue.
We, I ran a 4150lb race car for many years with a 5100 stall converter and a transbraked torqueflite. Every few weeks I had to pull the trans and fix the inner sealing ring of the high clutch to stator support . I had already went to stainless but the seals would begin to fail and it would show up in my MPH by a unexplainable sudden loss in MPH. Got so I knew what to watch for and just dealt with it. One day a local oil dealer brought Mobil Engineer the late Mike Priest here. It was obvious he was drag car savy. He asked if I had high clutch troubles and I explained the above. He asked why I didn't use Mobil1 synthetic . I poo pooed it but he issued me the challenge quoating the figures I mentioned above. Back then it was about an $80 touch to use it. I swallowed hard and gave it a try. Five years later I was on the same trans as it had not had to be serviced since. In spring checkover even the kickdown band did not require adjustment. Eventually I broke a rear spraque and had to remove the trans and replace the sheared case however even though I checked them all none of the clutches or bands needed replacement. I since decided that that trans probably took more abuse then any other I will own however I still use synthetic at least in all my race trans. The doorslammer car used to run 1.52 60 footers at 4150 lbs race weight carrying the wheels sometimes a foot in the air. My pal Gary also uses it in his BB Mopar RED which we adapted a heavily reworked 904 trans to. I don't think it would survive otherwise. His car is an old Woody G touring car which was built to survive and has. Not particularly light for RED.
For me it was the cheapest $80 I ever spent.

Dolmetsch, that's an interesting experience. Do you mean the Mobil 1 Synthetic ATF?
