I have 2004 5.9 305/555 auto 4 wheel drive 93000 miles.
Truck has been well taken of and runs fine. I have added a HE351,Smarty Jr,4'' back exhaust. I tow about 12-14000lbs 5th wheel.
I am getting ready to do a trip to Fl. and a trip to the west coast and back. I was looking at upgrading the tranny with a valve body and tripple loc converter.Do you think the tranny has too many miles or should I do a replacement Goerend.
The Goerend sounds great but $5000+ is a lot of money to part with. Where do you find is the cut off mileage for a upgrade or a swap.
Any advice would be greatly appreciated.

 

i'm not an auto tranny guru but i would say if it is not given you any fits then putting those mods on it shouldnt be a problem.

 

Thanks for the reply rich.
It is a big decision money wise.
