Re: Which Transmission is right for my application?
As 700r4's go thats a good price with a lifetime warranty.
Based upon my research the 700r4 have many weakness'
The input shaft and the sunshell are normally the 1st to go (it does not look like they use the better components in this transmisson for that part - the stuff they list is good though) - next is pumps and planetary gears.
The T400 is a power hog and for your application is over kill - you should be able to find a T350 rebuilt with a better modulator, shift kit and extra clutch packs for around 600.00 and another 350.00 for a converter should handle the power you have.
My T350 is abused with 490hp & 540 TQ with huge tires and I am on year 3 with it.
T350 take about 50% less HP to turn than a T400
