Well this was my thinking before today anyway. I am running 275/60/15, and plan on sticking with that size tires. My truck has about 325 HP, so about 75 ish over stock maybe. I had 342s but now have 373s in the diff. I have a truetrac limited slip in the diff now. So what ever I gained by going to a lower gear ( easier to turn) I may have lost with the LSD because of both tires biting, IDK. But bottom line is, I got over 250,000 miles out of the OE trans, even with my lead foot and the mods I have, so shouldnt I get more than or at least that much millage out of a performance reman. As for going with a 4L80E, well being my daily driver, I really just dont have the time for the truck to be down long enough to get one, not to mention all the extra things thats needed to do that swap. Being down to just the wifes Toyota, it makes it tough to get anything done. I ended up borrowing a friends Ram Megacab. He is all good with me using the truck for as long as I need, but I dont want to abuse that privdladge. I will only go back and forth to work in His Ram. Doing the reman, is the quickest way to get my truck back on the road. Doing the perfornce reman is about the best I can do, so that will have to work.
