I have an automatic, was wondering if you would use a window switch or not.

 

I run one...Anything that can help prolong the life of the transmission is worth it IMO.

 

Yes, spraying threw shifts is hard on the tranny.

 

YES! Don't want to spray too low and you also want to cut off the spray before your motor could hit the rev limiter. If the tranny were to let go in the middle of a pass, you don't want the motor hiccuping against a rev limiter when spray is involved. In other words, you don't want a blown tranny to take the motor out with it.

 

Sweet guys, thanks for the advice.

 

Check out the trick performance one available through nitro daves. It is a window switch and tps switch in one unit. Super easy to use, I change my window switch settings at the track all the time in about 30 seconds. All digital, no resistors or anything. It costs around $130.
