trans fluid???

[mikeT]

getting ready to put in a P/G w/transbrake and wonder what fluid you guys prefer? Have been thinking about Redline racing synthetic??

Mobil 1 works just fine and is cheaper. Synthetics will lower the trans temp.

What kind of a car is it?

I'm using Hurst Hot Shift, because it's the only thing I could get my hands on at the time. But I'm fixin to change.

How about the John Deere Hy-Tuff hydraulic tractor fluid? I hear it holds up very well. And just put a quart of regular red colored fluid in with it to give it some color so you can read the dip stick better. Anybody heard of this?

[John_Heard]

I've used it before (the John Deere Hyd Fluid). Smoked 2nd clutches in my 400 with it, but I don't really think it was the fluids fault. Regardless I wasn't ready to risk it again and went back to regular Type F. On the new transmission I'm putting in I'll be using the compressor oil.

AMZOIL is great stuff also and i think Neal racing transmitions I belive recomends it and also I heard about the John Dearworking well and a Cat. hyd. fluid.

I use Mobil 1 synthetic.

I've heard from a lot of locals around here that you shouldn't use synthetic oil in your tranny. It's fine in your engine and 3rd member but their reasoning was it makes your internals too slippery. I'd be interested in some feedback from you guys. I'm almost ready to fill mine up and was wondering what to use as well.

One other question after reading John's link...Will the Amsoil comp oil work in a high performance TH400 or is it just recommended for glides?

[John_Heard]

It'll work in a 400 same way. Note: You do want to warm the transmission up with that fluid before making passes, it is a thicker fluid than standard ATF.

I use the CATIPILLER to-2 oil. no issues yet. not bad priced compared to the specialty stuff. i think it was almost 50 dollars out the door for a 5 gallon bucket.

been usuing dexron 3 with no problems...then tried royal purple synthetic and the et fell off bad....changed at the track back to dexron 3 and got the et back........have a friend usuing amsoil syn and he loves it........never know on some of this stuff until you try but on the other hand sure a waste of good money if it doesn't work

neils racing transmissions suggest straight type f in their powerglides

I have been using TCI RTF Trans fluid in my TH400 and having good luck with it.

Been using this stuff for years!! I get it at Tractor Supply
