How long will my 4L60e last? I just had my car tuned a couple of weeks ago and he turned off torque management. The car shifts ALOT harder at wot now, im just wondering what I can be expecting in terms of transmission life? I have factory 3.23 gears and street tires. The cars stock for the most part at the moment and will most likely be getting 3.42's headers a lid and catback here shortly. I have 104XXX on the car now. Would adding an external trans cooler and switching to something like the TCI fluid help to extend it? Im racing the car a fairly good amount and I realize stuff is gonna break, Im just kinda wondering on a timeline. I use BG synthetic fluid in it at the moment changed every 30k since the car was new.

Your going to want a cooler on it first thing, that will make or break transmission life. Shifting harder is good because there is less slipping/wear going on(not forgetting that this can be hard on other parts I guess). With the fluid changes as often as they have been, and then add in a cooler -- you could be on this transmission for a long time to come. i will leave timeline guess for others

Can you get your tuner to put some shift torque reduction back in... ?
It's shifting harder because the PCM is now not reducing ignition timing on each upshift.
The purpose of shift torque reduction is to protect the trans stock internal hard parts and the stock 10 bolt.

Im not really worried about breaking either one because I plan on replacing them with built units anyways, I just wondered what kind of timeframe I might be looking at. Im ordering a cooler tonight and im due for another trans flush.

Get a transmission from Performabuilt. And put on a big oil cooler and you'll be set. Mine has worked great even with repeated abuse from 1/4 mile runs and roll racing. And that's with 560-700whp. I even hit it with as much as 800lbs of torque in 4th gear at the track and it didn't mind it.
