OK, this year I'm going to bite the bullet and replace my transmission. I have 170,000 miles on what I believe is the original transmisson. For once, I want to replace something before I start having problems instead of on the road somewhere in semi emergency conditions (like I had to do with my lift and VP44 pumps, another story). I'm retiring soon and plan to do a lot of towing a 38-40 ft. trailer, so I want the best transmission for towing, exhaust brake and locking torque converter. I've been looking at the adds in TDR but of course they all say the're the best. Any suggestions?
