4r100-are they just not a tranny made for a lot of power?

Whats the big issue with the 4r100 when you put quite a bit of power behind them? Is it the valvebody in them setup not to have a lot of line pressure and causes these trannys to give out kinda qiuck?

This is what i have been told by some ppl in the past but wanted to clarify that.

They have always been the weak point of a F250/350...the 6spd on the other hand can handle more. I don't know what the issues are.

If you call over at Brian's Truck Shop, bet he will give you the run down...he specializes in these.

Well first off the 6 speed isnt much better cuase you still have to upgrade the clutch. Now the auto is weak once you put some power to it. A built auto will pull circles around a 6 speed anyday of the week. BTS is a great transmission

Whenever mine goes...144,xxx, it will be replaced by a BTS!

How much power can these hold in stoke form. I have a triple dick torqe converter with dp tunes and a 38r. How long do you give me on the stock box. It has 110000 now

Hard to say...have you owned it since day 1? Do you tow? Depends on what that skinny pedal does too. Doggin' it all the time isn't gonna help...just sayin' not that you do or anything lol

Thats pretty good. Well I've heard of people just putting in a triple dick converter
