trans rebuild

[grumpyvette]

eventually if your running a car with significantly higher than stock horsepower your going to find the STOCK transmission giving you problems, its not a maTter of if...ITS when!

HEAT AND TORQUE LEVELS ARE THE MAIN FACTORS that destroy a transmission so don,t fall for the total bull $hit of advertizing on hp levels

the transmission has a torque level that the parts can stand long term, a th350,700r4, 4l60E,200r4 are all rated at 350 ft lbs in stock form, all can be improved but NONE will have the strength of a properly rebuilt 4L80E or TH400

theres just much more massive parts in the heavier duty transmissions , so before you rebuild your current trans think thru the goals.

example

the formula for hp is torque x rpm /divided by 5252=horspower

so

350 ft lbs at 4000rpm =266hp

350 ft lbs at 6000rpm=400hp

500 ft lbs at 4000rpm=380hp

trust me the 380 hp combo will twist a 700r4 to scrap well before the 400hp combo will

IM sure theres several guys on the site that can add a great deal to this thread and I welcome thier input here as transmissions are not my strong suit!

in fact ID love all the info I can find on making a 4L80E full manual control as Ive got a new 4L80E I purchased from the local chevy dealer at a discount,for my BBC corvette engine swap project, and ID vastly prefer full manual control over an electronic control I need to program to get the trans to work, both due to the cost (about $1000 for the controller) and the better actually control on the car, If the driver controls the shifts
