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.

i am glad you posted this. Paolo and i were talking tranny fluid, and he said he just put in RedLine's and he loves it. really smooth shifts and whatnot... i am curious as to what others say

 

[Mister Bone]

Just make sure it is compatible with your syncros. I can't remember which it is, GL4 or GL5, but one has an additive that will eat up the syncros.

Bump.

C'mon folks, speak up. Give me exact type too - like I know Redline is good but what type of Redline, etc.

What type does it call for?

GL4, GL5, what?

Then I can give you some info Mark.

But I am sure owners will give you something else to go with mine.

I don't have the manual in front of me Jerome - I'm waiting for someone to pipe up and say "I use this and its great, go buy this".

 

[Mister Bone]

When you say manual do you mean service or owners? It should also say in the owners if you have one. If not just tell me to fuck off. /images/graemlins/laughing.gif

So Mark I will take that as "Fuck off" /images/graemlins/laughing.gif

Don't screw with your tranny...use factory fill here. It's synthetic and you know that additives are right.

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.

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!

AWESOME. Thanks for the info Paolo, this is exactly what I was looking for.

I used D4 ATF and did notice smoother shifting, but more noise.

Re: Lets talk Tranny fluid/ Redline D4 ATF

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?
