What is the THICKEST, TOUGHEST oil I can put in my viper trans??
Im doing some standing mile racing (200mph speeds) and i want something that will help with overheating. I know that a fluid pump would be ideal, but thats not an option right now. Im currently running GM Synchromesh. I was thinking about adding some lucas trans stop-slip (super thick & sticky additive).
any ideas on what fluid to use? the trans has all carbon synchros btw.

Thicker does not necessarily mean better... Just run a quality synthetic like Amsoil, RP, etc. I used Pennzoil Syncromesh and have no problems over many years. Great smooth stuff, but I hear the Pennzoil = GM Syncromesh

And while he was asking about fluid, he was asking about fluid for a specific transmission, not just a random transmission, and certainly not a sequential gearbox.
From what I've found, the Dodge recommended Viper factory fill for '03-'06 Vipers is Castrol Syntorq (75w85)...that's far thicker than the Dex III ATF GM recommended for T-56s over those same years. I would guess Pennzoil Synchromesh is somewhere in between the two.

Couldn't tell you how the Syntorq feels...'08 is when Dodge switched to the TR-6060 to handle the extra HP ('08 was the first year for the 600HP 8.4L engine), and they also went back to a thinner fluid. From what I've found, Dodge went with the Syntorq to quiet down the neutral gear rattle noise that a lot of Viper owners dislike, but I'm guessing the thicker oil and the TR-6060 don't get along very well. My transmission definitely rattles in neutral, but it's just how the transmission is.
