i still have my forged 370 in the truck looking a putting a cam and a little stall in it. i put the stock trans back in a sold the level 6 rpm, how much of a shot will the stock trans take with the line psi turn up and a vette servo?

 

i think its relevant, not really a good answer. some stock tranny's blow out with stock motors, you have a 370 in a CC truck, heavy + power = breaking ****. i have been spraying a 125 shot with my mods in sig, around 420+ rwhp, with no problems... knock on wood.... i have 43K miles on my truck now, and its my DD to and from work. i dont spray off the line, and i dont spray through the shifts... i hit from about 3K-6200 rpm, and its been able to hold so far.

take that for whats its worth though, i dont really know if the servo will help as far as increasing life, just shifts a bit firmer.

i would start saving for another tranny for sure while you play with the stock one in though. it wont last forever. put yourself a large tranny cooler on it and get your tune dead on, and hope for the best.

 

its been a good one it took a STS turbo running a 7.75 in the 1/8 mile! i just new it would not last long but the motor blew up first. then it took 490hp from a radix and still shifted good, but took it out after buying a $3200 4l65 from rpm but sold it and when back stock. so now i can not take it no longer....i have had the turbo, radix,prochargers, but i have never used nitrous!!! just looking a little jump!!

thanks for the help!

 

i have been sprayin thro the shifts with just a 100 shot for now and sprayin off the line and so far so good and after i make a pass i give it thirty mins to cool down before i make another pass.. and i agree i would start savin for a tranny which is wat i am doin.... but id get servo and a bigger trans cooler.

 

my 6.0 with a 150 shot lasted 2 weeks

 

Avg about 2.5 a month.

 

I bought my truck with about 50,000 on it, 01 ECSB 5.3l

I put a B&M on the hard setting, and a vette servo in, and was worried about popping the trans with nitrous.

I sprayed (IIRC) an 80 shot, about 40 feet out of the hole, all the way through the shifts, stopping at about 90mph. Ran a 14.8 running really rich and with a 2.3 60ft. Never got a chance to put slicks on it. The truck has about 60-70 1/4 mile passes on it.

I tow my race car quite a bit with it, and drive it to work every day. I now have 98,500 miles on it. The fluid looks/smells great, and the truck runs great. I had heard that the B&M would pop the sun shell, all it does is pop the tires on a WOT 1-2 shift. Same for spraying and through the shifts, but it runs great.

 

Mine lasted 30 minutes after putting the 6.0 in my old truck.

 

if you don't spry throught the shifts and hit it rolling, it might help it last longer. but a stock trans is still very weak

 

IMO save yourself the hassle of a blown trans, just wait until you get a built one.
