tranny
 

seeking information on Transmission. I have a 07.5 Bombed 150,000 miles, original Tranny. Rebuild? or purchase aftermarket? Mostly used for towing, but has a tuner with four settings. Would like a trans that could handle the hotter settings, I keep it in tow mode 99% of the time. Would appreciate any tips, knowledge on the subject or referrals.
Thanks
