[SS/GN]

Is this still the best?I cannot find it in 1 quart bottlesThanks

When I posted this question earlier this year I was told Dextron IV was the best. I have been running it since and have not had any problems.

Canadian Tire here in town stocks it.

i will go with that oil after a lot a search on turbo board

Oil and Lubricants : Hydraulic Oil

i will get the low viscosity in my fresh th200 rebuilt

the standard viscosity will tight the convert from 200 rpm

i will switch to that one if it need

imo

I too search and found this write up, and now I have been using Type "F" since I also installed an tranny external cooler.

john deere tractor hydraulic fluid here. it works flawlessly even when beaten with the high temps of using a trans brake

Thanks for the input,I ordered some in through Napa:biggrin:Many many opinions on oil.I was over on bullet and a tranny guy claims Redline synthetic Type F is the best.Combination of friction modifiers and helping to reduce thermal breakdown.Thanks again

I run Type F in all my junkers. Works great!

I think I buy it from Wal-Mart...

I'll NEVER run "F" Ford fluid again!
Why you ask??.....My tranny shifted nails with old GM fluid.....then I had this brain wave "cool guy" thought of changing it out for the "F" fluid. Trans has shifted and flared ever since.....what does that F stand for anyway....... I'll stop now.

This seems very odd as Type F will shift more positive as it has no friction modifiers like the dexron 111 has.

Woops... dbbl post, sorry.

a friend tell me it NOT work good with a lock-up converter

in the 70's when ford first built the c6 transmission and put it in vehicles customers came back saying that it shifts too hard (like we like them to shift). so ford made the type-f fluid so the c6 transmission will shift softer.

For years we ran "F" in our street and strip cars.

When we arrived in the 10's and 9's then problems began.

Racing, especially the launch, develops high heat VERY quickly, and heat is the deadly enemy of trans fluid.

The real "eye opener" was a couple years ago when I took a customer's 9 sec. GN to the track with a very expensive built TH 400 with a trans brake. The builder recommended we use type F.

We made about 5 test passes and the park pawl bolt came loose. Back at the shop we had to remove the pan to tighten it.

The fluid was black and burned after just that outing.

I had been running Dex VI for over a year and 200 9 sec. passes in my TH 400, and then I decided it should be changed, it came out as red as it went in! :biggrin:

Bottom line, for over 2 years we have used Dex VI and and have experienced much longer life on both street and strip builds. :biggrin:

Nick thanks for the heads up but isn"t the dex 6 slippery because it is a synthetic and therefore allows the clutches to slip creating more heatWe always used Type F in the race car but it never had a lockup in it.As always I look forward to you input

Kevin

FYI I see redline oil has full synthetic type F

Here is my "take" on your question.

Type F was done in the 60's for the then current transmissions and friction material.

So here we are 50 years later with MANY developments and improvements in oils and materials, and different requirements.

My clutches, which are not stock, last MUCH longer, car runs just as good or better than with Type F.

GM must feel about the same since they have very complicated and intricate transmissions which must last through the warranty period which can be 100K miles, and they have a few performance models which will kick ass on a stock GN!

I know lots of Buick tranny builders around the country, and all say use Dex VI. If there were reported problems, we would hear about them. All I hear is good stuff when using Dex VI.

As far a Redline synthetic, the marketing guys are always looking "better" ways to penetrate the market? :biggrin:

Thanks Nick muchly appreciated

Nick, we really appreciate your opinions.....thanks.

 

[Mr.Spool]

here is something to consider,the redline racing type f is full synthetic and according to redline all their synthetics take the heat the same,d6,d4,etc.the difference is in the viscosity,and how much initial hit on the clutches a person wants.
