[DML] Re: stage II - Automatic?



Full synthetic oil will add considerable life to the automatic and 
let it run cooler. The torque converter heats the fluid quickly and 
constant heavy load will generate some very high temps (over 200F). 
The synthetic fluid will resist breakdown and burning of the 
clutches. There is so much heat generated you have the potential to 
overheat the engine since the cooling tube is before the engine.

I have experimented over the years with my automatic and observed 
others. I have run mine very hard at times, etc. and there are some 
things, in my opinion, you should and should not do.

DO - use synthetic fluid and provide some sort of additional cooling 
CLOSE to the torque converter. I use Grady's cooling fins for the 
tube - it helps some - and I put a flush-mount trans cooler on the 
outside of the frame behind the shock (you can barely see it from 
behind and looks normal - nothing ugly - it is a custom car aluminum 
type). This gave me another 1/2 to 3/4 quart of fluid and removes 
some heat BEFORE the cooling system cooling tube which I left 
functional.

DO NOT - use a trans cooler that is mounted on the front of the car. 
My observations are that this will cause the trans to fail. The pump, 
in my opinion, cannot handle the fluid movement over that distance. 
I've seen too many fail with one of those things mounted up front.

DO - disconnect the "kick-down" switch on the throttle cable spool. 
The kick down, again my opinion, causes harsh shifting and can cause 
3 to 1 downshifts and up-shifts which, in this trans, is destructive.

BTW I don't think my automatic is a slug - I'm probably quicker than 
most 5 speeds 0 to 60. (that's right!)
