[QUOTE="kickdeez, post: 1571127, member: 8244"] In need of some advice/knowledge. I come from the world of toyota 5 speeds and doublers on doublers. Just got into a new (to me) buggy with an automatic transmission that I need to have rebuilt. Relevant specs are: [LIST] [*]700R4 transmission [*]RMVB [*]Low to middle 2000 rpms stall converter (not entirely positive) [*]B&M Super Cooler with fan on switch...Temps generally stay in the 160 - 180 range [*]5.38 axle gears [*]Atlas 2 speed with 4.3 low range [*]More or less stock 5.3L LS [*]Currently 39" reds, but switching to 42" Treps [*]3,800 lb rig [*]80% crawling, 20% put my foot through the floor cuz I like the sound it makes, and that's just east coast wheelin. NOT a bouncer. [/LIST] Transmission was rebuilt in 2019, and performed well until now. When I got the buggy, it was slipping in 3rd gear. This weekend it completely grenaded. I think I'd prefer to get this one rebuilt as strong as I can get it, as opposed to swapping to a different transmission. Swapping is just a ton of re-configuring in an already tight package. Certainly these 700R4s can be built to be strong enough and reliable enough for a crawler, right? I know they have gotten a bad rap for a while, but I was reading that it was primarily the result of poor adjustment of the TV cable. My questions are: 1. Who are the go-to transmission builders/re-builders on the east coast? The closer to Charlotte, NC the better. But I'm certainly willing to drive or ship this transmission to the right person for the job. 2. What parts/upgrades do I need to be familiar with and make sure are included in a rebuild? Assume that I know zero things about automatic transmissions. 3. What rpm range should I be in for the stall on the converter? 4. Is 3ish years a reasonable life expectancy out of a "built" 700R4 for what it's being used for? Just want to make sure I prepare myself and budget for major maintenance items appropriately. 5. Should I be considering a new unit from like TCI or Monster (or other performance transmission manufacturer) instead of getting this one rebuilt? [/QUOTE]
