One more LubeGard question

[doug]

I recently fried my tranny and had it replaced. The tranny shop I used, which has done DSM-related A/T work before, recommended straight Dexron III synthetic fluid (Mobil 1, I believe). I asked about the addition of a bottle of LubeGard black, like I had been doing on my own since I saw TransDude's recommendation. They told me that on a stock tranny it's fine, but on a tranny that is mated to an engine producing significantly more HP than stock, that the LubeGard should NOT be used since it increases the "slipperiness" of the fluid, which on a higher HP setup is not a good thing.

I always knew that LubeGard was a friction modifier, but I was never sure exactly how it modified-- I had always assumed that it made the fluid LESS slippery. What's the deal with this, and does this tranny shop know what they're talking about or not?

Some trannies are seem to be fine with just dumping in the synthetic without using the lubegard, but why risk it? Use the $15 to convert it to ATF +3. It's a Chrysler thing. I've used the Trickshift in my 97 Spyder and ran it for 15,000 miles before I sold the car and it never had any problems and then I read about using the lubegard and have used it ever since and have had no problems. I rather be safe than sorry. It's not going to hurt it. You can read on the bottle that it just converts a Dexron III compatible fluid to ATF +3 which is what Mitsu and Chrysler want.

Why would you want to decrease friction (holding power) in a tranny that's trying to push more HP?
