How often do you change trans fluid while at the races?

RocketBlock · 05-09-2007, 05:48 PM

I hear a lot of super stock racers are now taking the time to change their ATF fluid after making qualifying runs at the races. Some racers are even being spoted dropping the pan more than once! That's good maintenance which should be good for long term reliability of these expensive transmissions. Glad to see some of these young racers still don't mind getting their fingernails dirty.

I DONT UNDERSTAND WHY YOU WOULD HAVE TO CHANGE THE TRANS FLUID THAT OFTEN UNLESS YOU ARE CHANGING SOMETHING IN THE VALVE BODY THAT CONTROLS THE DELAY OF THE TRANS BRAKE. YOU DID SAY SUPER STOCK AND NOT STOCK. SINCE STOCKERS DON'T HAVE TRANS BRAKES WHAT ELSE COULD IT BE???

Fluid lasts much longer than that , unless subjected to extreme heat. Sounds like overkill to me.

Yes, with the cost of fuel and traveling, that's one area they could save money on! Some of these racers drop the pan to change the fluid. You would think they would get a pan with a drain plug! And some of them seem to change just a little fluid by removing the trans brake solonoid a few times each race. I guess after you drain a little out each time by removing the solonoid it ads up to the same as draining the pan all at once. I guess it's a personal preference. Glad maintenance is such a high priority!

Are you suggesting that the odor of cod liver oil permeates the air when making these observations? This does sound unusual![:-bighat-:]

Rocketblock your stirring the pot .... But your close to being correct

Sometimes it is easier to control the transmission temperature, by changing to cool new fluid. If you can control the fluid temperature the transmission will be more consistent.

With all the aluminum in my lite-weight trans, I notice a lot of metallic substance in the fluid. I change it every 15 or 20 runs, not a big deal at all.

Oh RocketBlock, watch what you get in to here. Some people might take it personal. Would be interesting to see what there qual reaction times are in comparsion to their first round. But I have heard stories of a guy droping his pan every run...and the out come was winning A LOT of rounds!

IN LAYMAN'S TERMS ARE YOU SAYING THERE'S SOME TYPE OF A ADJUSTMENT BEING MADE (DELAY) TO THE TRANS BRAKE BY DROPPING THE TRANS PAN ???
