Thats why the aftermarket companies have stepped in.
I realize everyone is loosing there overdrive clutches etc,but who is to say the stock converter is not part of the problem.???
It just desnt make sense putting in a built tranny capable of handle 500 RWHP and keeping the stock converter.???.
Thios is the same converter that goes back to 1999 I think.?
Im pretty sure the motors back then were not running 500 RWHP.
Anyway just my take on it.
Not trying to be a smart ass.
I have towed several 18,000 lb.GVW loads with my Circle-D triple disc converter,I dont think the stock converter would even come close to handling the weight.
With 70,000 hard towing miles on my 545rfe,the weak link is not my transmission,but I bet it would be if I still was running my stock converter.
Anyway awesome build,best of luck to you.
The converter locking in 4th burns up the od clutches, and the r/t converter locks as much as the after market converters to accomplish this on a stock trans.
Also, I pulled a bread truck out of 4ft ditch in 1 1/2 ft of snow with my r/t converter with no issues. My truck has also had plenty of hard towing miles for my business/step dads farm and has never had an issue with the converter.
