So my shifter is telling me its time for new tranny fluid. Is RedLine safe in the Viper tranny? I really like RedLine's products and would like to go with that but I seem to remember way back when that certain fluids can be corrosive to parts of the Viper's tranny. I need something thats good for high-heat track days.

Mark, I have a friend, Geoff, who has taught me many things about cars and he loves all the Redline products. I remembered something about the Desert venom guys not liking the Redline products....

After reading the literature on the Redline website in regards to the trans fluid, I learned a few things:

1. Most people(including myself) think that slippery(er) is better.....==> Not actually the case. There actually needs to be a certain amount of friction for the synchros to match speeds in order to get it into the next gear...

I talked to Bobby Archer about tranny fluid after going to the Redline website.

Bobby said they use the Redline D4 ATF in all their race cars and have not had a trans failure yet.

I put the D4 ATF into my rebuilt stock unit and it shifts like a motherfucker!

At this point, I have to also consider the fact the guy doing the rebuild also did some modifications to the synchros and setup of the trans internals. So part of the shifting ass kicking-ness must also be from this.

I have a friend who has a stock trans and we will be putting in the D4 ATF shortly to see how it works in a totally stock unit.

if you have any further questions, I would call Bobby Archer. He has given me the best info so far.

P.S. He also sells ALL the redline products by the case!

But does this work for all car through 2002? I have heard that 99 or 2000 cars require Syntorque or something similar due to the nature of the materials used in making the gears.

96 R/T 10, I believe they changed to the syntorque to minimize the neutral gear rattle as well. I do not believe there is any difference in the gear material for the 1999-2002 trannies. I would call Bobby Archer to be sure.

BTW, here's the link to the Viper Fluids maintenance info I put together from various sources:

http://www.yandros.com/Viper/ViperFluids.htm

Sounds like I need to add the Redline to the list. What's up with the "noise" that DChan mentioned?

Oh, and does anyone have a listing of the transmission fluid changing process?
