It also depends how you drive. I ran plateless w/ 4k gsk and 370s for awhile before I started slipping my stocker, it probably lasted because I never felt the need to go from 0-100 in xx amount of time and race all the time, like some people do...

Like I said above, I ran some power through my stocker, and it took the 370s to finally slip it. What it comes down to, is how your drive it. If you yank the plate, and start hammering it 24/7 don't expect it to last long. Now if you take an easy on and screw around here and there it'll last to a certain degree but it'll still go out. Ultimately IMO it's the driver who decides how long the stocker will take the abuse. Just pulling the plate, and driving down the road doing the speed limit won't make your tranny slip, but if you pull out of the driveway and punch it etc, then yes you will have problems. With no plate, your tranny will run hot but it can be controlled. Like in town, drive with the OD off. It'll lock the converter sooner and allow it to cool down

My 96' has 210k miles on stock tranny, added a few turns on my p-pump and 200 miles later, Needs some new internals. He could not have said it better "Stock Tranny, Stock Engine" Build your trans first, Then Build the motor.

tranny first,,,, the torque converter will slip, and the clutches will burn,, also upgrade the valve body with a good shift kit or for the price or order a replacement,also the lower planetary/sungear assembly will need to be upgraded it's the weak link in the bottom of the tranny, have fun bud,,, i can say i have been there done it , got the recipts of the pain,,LOL

go get your tranny done first then do the motor i found that out the hard way and dont just buy the converter buy a dunrite valve body and put that in it doubles ur pressure and also acts like a standard best thing i bought for my truck so far THANKS VANNEST
