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

Thats pretty good. Well I've heard of people just putting in a triple dick converter and its to strong for the rest of the stock parts. I may have just thought that in my head but im pretty sure I didnt...
