i just installed a new fuddle 3600 stall 2.5 str,well when i push on the gas hard sounds like a grinding sound or like a swoosh noise only when you step on gas,does anyone or is this normal

 

anyone

 

Not normal, check your fluid level. How much did you put back in?

 

Did it install correctly. Pushed ALL the way onto the input shaft? 3 clicks?

 

yes it did and i added three quarts

 

im thinking it might be the muffler pipe rubbing under the car under load due to engine moving

 

nastynate what youre rpm at 70 mph,mines at close to 3000

 

Damn 3k what gears are u running? Is it the stock 4L60E?

 

3.73 with 275/40/17 tires

 

yeahp stock 4l60e

 

Thats alot of RPM man, maybe ur **** isnt locking up, im at about 2450 going 70 with my 3.73's.

 

just to add this my car has 3.42's at it tachs 2000 @65mph and I think 2200@70

 

gt griller dou you think because its a 3600 stall and how can you tell if its locking up,it may not be due to the computer possibly

 

while crusing at 70mph keep your foot on the gas and use your left foot to lightly apply brakes and see if the rpms go up if not then its not in lockup .I think 4.10 would be around 3k @70

 

mine is about the same as 2200 at 70mph with the ss3600

 

When slowly accelerating u should almost feel like a shift into "5th gear" no theres no 5th but its when it locks up it feels almost like it shifts again.

 

i just tested and around 40 it locks up then you step on the brakes and you can see the rpms go up from 2000 to 2400 so it is working but possibly at higher speeds the computer is not letting it lock or something because the rpm are at 3000 at 70

 

set the cruise(sp) control at 70 and it will lock no doubt...and if it says at 3k then either you have a tuning,stall issue or you have 4.11s...IMO

 

yeap thats what i did set it at 70 and it stayed at 3000 for a while then it drooped 2400 or 2500

 

Also the computer will not lock the TC until your transmission reaches a certian temp so if the problem is only in the first mile or two then that could be your problem.
