There's no such thing as new transmission 4 ur vehicle, it will be a factory rebuild, what r u being told is wrg with ur trans (only skimmed all the posts so if u said i missed it). I know ur in situation where u need a fast turn around but the r better options then a factory rebuilt. There r two company's that offer upgraded TC (torque converters) and increased # of friction disc's. In ur position u'd be better of getting a cheap used trans and running it 4 a while, while u info urself about what ur needs r (how ur going to use ur vehicle and what u need to upgrade/build to fit ur needs). There r a # a other factors that one needs to take into considerations when parts start failing on their vehicle other then saying "u bought a lemon", what i mean, is that what caused ur trans to fail, heat is generally what is going to kill ur trans. Ur added weight and not understanding the effect it has on the rest of the drive tran, along with improper driving habits and expectations of ur vehicle. With the proper upgrades and adjusted driving habits this vehicles can safely and dependable handle a lot of weight (my 3rd gen is both a overland and very capable rock crawler but this requires a lot of work, and adds tons of weigh... literally). Back to trans heat, when adding weight and not watching/understanding how ur trans is affected, ur going to quickly kill it, I could write a page on this alone, this transmission r very easy to work on and there r a lot of ways u can help the unit to last. One of the best mods i did was to add an idiot light 4 TC lock up, when ur TC is in lock up the heat being generated by said drops to very small amounts, this give one a visual stimulant and teaches u where to hold ur foot on the gas pedal. There r a # of other things that will help with heat but ive already rambled to long.
ur rear diff is another point of failure that isn't surprising, depending on ur uses, weight, and desired 4x4 ability. An upgrade of the axle assembly and all the components associated with said will need attention. I put a tundra 10.5" rear axle assembly into my 3rd gen and have been very happy with said (its a complicated mod that requires the complete reworking of the unit and shorting it width), because i was destroying the stock rear ends regularly.
every build is unique to it owner and with that the type of repairs and upgrades r going to be based of what performance and function is desired.
