Got my BTS hat....

....and transmission.

Apparently my stocker was still in good shape, as I suspected, as there wasn't a huge difference right off the bat. What I did notice is the truck feels more connected and heavier, I'll try to explain.

Connected -It seems as though I can feel the driveline similar to that of a manual trans. The transmission no longer absorbs throttle changes but rather transfers the changes immediately.

Heavier - Maybe this is a figment of my imagination but the center of the truck just feels heavier. There is a definate weight difference between the stocker and the BTS, I could tell by just sliding the transmission in and out of the truck but I highly doubt I would be able to tell once installed, but I can. The weight difference that I feel may just be the fact that the truck is more connected.

Now, after about 150 miles and several heat cycles the trans does seem to have broken in some. On the stock trans there was quite a bit of difference between the converted locked and unlocked about 300 RPMs. Now, there is not much difference between locked and unlocked, only about 150 rpms at most. This tells me the TC is much more efficient.

The trans does run a little warmer, which others have report the same thing. My stock trans never got about 154 and the BTS seems to settle in at about 175. I may try a bigger cooler to see if it will keep it a little cooler but will try towing something first just to see.

Anyway, the best part is I don't have to worry about the trans.

The BTS in my 02 runs about 70-80 deg above ambient. It has a 6.0 cooler though. Was in the truck when I bought it. Hottest I've ever got it was 200 but that was after the 8th boosted 4wd launch at the strip. I agree on the more connected feeling though. My truck is much more responsive to throttle then papaws 01 that's all stock but a mild tow tune.

I did notice a couple other things....I build boost quicker and between shifts the boost recovers quicker.

My BTS and 6.0 cooler dropped temps about 30-deg from stock. Hottest I every
saw it was 180 after a long slow up-hill pull.. Then it cooled off within a few miles
of reaching the top of the hill.
Better have your foot on the brake when putting it in gear, it will take right off.

theres no comparison between my old trans and the bts i have now.... bts runs at least 20* cooler no matter what im doing... never been above 150* even towing my 36' fifth wheel in 90* weather this summer... hell it was a 115* in kansas this summer and it still never got above 150*... i have the stock trans cooler and a true cool auxiliary cooler in the front of the grill... way way tighter in shifts and lockup... when most people rude in my truck they think i have a 5 speed trans because of how hard it shifts and how hard it pulls after each shift and or lockup.... like said you better have your foot on the break when you put it in gear cuz it leaps forward. even with a trailer hooked to it on a slight incline it will move on its own... the old trans would actually start rolling backwards on the same incline without the trailer hooked to it. hands down best mod ive done to the truck!!!

With no changes at that point to the cooling side of things my BTS did run warmer then stock. I have been tool that is a result of the pump and running higher pressure. I do understand the more connected comment.

To be honest, when I first drove the truck there wasn't much difference to the stock trans. But I wasn't really having problems, this was a proactive repair.

After a few hundred miles I am very happy with the trans and can tell a significant difference. I am building more boost and building it quicker. Can't wait to get a chip and injectors.
