I'm about to finally install my Yank 4200 stall, and just wanted to know which is the best tranny fluid for a stock 4l60 with a stall?

 

Did you add an after market cooler..?

 

of course! I got Hayden cooler that is suppose to be for mobileholmes!

 

Dexron III or equivalent here. No synthetics for me.

 

has anyone ever heard of dex VI we have it were i work and it says its compatible with all gm but just want to make sure before i put it in

 

All the dealership are putting dex VI in transmissions now no matter what year. Its more $$ too.

 

kewl well were i am i get 5 gal cans of it for basically nothing at all just wanted to make sure it would work with my lvl2

 

interesting!

 

Dex VI is going to be the new oil that we are going to be seeing more of here shortly. It is just fine to use if you can not find the III.

 

ok so..... III first then the VI would be the next choice?

 

Dex VI user here..............better heat #s than III, Dexron-VI delivers ~two times the service life of Dexron-III H fluids

Buy it in the 1 gallon jug and pump away
A little info from last year..........

DEXRON®-VI ATF
General Motors Powertrain has recently upgraded to DEXRON®-VI ATF with the start of 2006 vehicle production.
Only 2005 and prior models that currently use DEXRON®-III may use DEXRON®-VI as a replacement.
All 2006 and future models that use DEXRON®-VI are to be serviced with DEXRON®-VI fluid only.
DEXRON®-VI is an improvement over DEXRON®-III in the following area:
DEXRON®-VI
Extended Factory Fill For Life 160,000 km (100,000 mi) For Cars and Light Duty Trucks*
80,000 km (50,000 mi) (Severe Use) For Cars and Light Duty Trucks*
Clutch Friction Stability Improved 100%
Clutch Durability Due To Fluid Improved 120%
Oil Film Thickness Increased 20%
Fluid Oxidation Improved 100%
Foam / Aeration Improved 150%
Shear Stability Improved 200%
* These ATF change intervals remain the same as DEXRON®-III for the time being.
2006 Transmission Fill and Cooler Flushing
Some new applications of the 6L80 six speed transmission will require the use of the J 45096 -- Flushing and Flow Tester to accomplish transmission fluid fill. It is highly recommended that the clean oil reservoir of the machine be purged of DEXRON®-III and filled with DEXRON®-VI.
