I have a built 700R4. I was curious as to what it can hurt on the tranny if I sprayed through the shifts.

 

Well depending on how much torque you are making at the shift points will have a lot to do with it. But the weak points in the tranny are going to be the planetary or sprag I would think. I used to run a 700r4 behind a 396bb in a chevelle with a 150shot years ago and it held up pretty good. Never got off the spray while making shifts unless the car got loose.

 

I have a built 4L60E, I spray through the shifts, no problems yet, car shift just as quick and hard as ever.

 

cef97ws6 said it well. I'd be cautious with a hi-po setup spraying through the shifts on a stock tranny though.

I am about mid to low 12's on motor only. I havent able to get to the track since a few mods. I have a built 700R4. Looks like I will find out in spring if it will handle it

 

My built 4L60E hasn't had a problem yet running 11.0's. I spray out the hole and through the shifts. If I ever get the tires to hook on a nitrous launch, I should see 10.80's with the traps I'm running.

 

Are you pulling 1.61 60fts on the stock rear?

 

I run a 175 shot and always spray thru all the shifts.

 

Yes, I've pulled a best of a 1.55 60ft. on the stock 10-bolt.
