Re: Knowledge Is Power: Transmission Life Expectancy Chart

lol heres a funny story for you....

i was driving my gta today, with my new b&m trans cooler. the new transmission in the car is doing great, shifts hard, it was just an overall good time. all of a sudden, as im backing out of Mc D's, i see a bit of smoke come from the hood scoop. then a bit more smoke. i swing back into the parking spot and get out. about 3 qts of trans fluid on the ground and about 2 gts covering my engine bay and engine. i blew one of the lines off the new cooler then the fans sucked in the fluid and sprayed it all over my car.

guess its time to clean the engine bay again

i just swapped the cooling lines in the parking lot, filled her up, cleaned the bay out with a rag, and limped back home.

and everyone knows how headers and one drop of trans fluid looks when they are together

good times, still love the car, still love the cooler, and still love the new trans

there are much more factors then just heat. you also have to take into consideration: how hard the tranny is used, what size and stall torque converter, what kind of power/traction ratio it has to deal with, regular fluid and filter changes or not.

all of those would change the life of a tranny greatly. that temp theory might work if you're assuming it has regular fluid and filter changes, and some old lady driving the vehicle.
