TCI heavy duty 904 rebuild kit will make tranny handle 550 hp

TCI from my perspective; I bought an HD 727 from TCI a few years back (3-5). I put it in a basic stock 318 71 Duster, the only modification was an LD4B intake & a 650 VS Holley. I installed it per THEIR instructions & used the fluid recommended, put an after market transmission cooler on, hooked up & installed the kick down linkage, adjusted it per the instructions & returned the car to it's owner. The transmission lasted about 10 days of mostly around town driving with a little highway driving. The customer brought it back complaining about slipping & over revving the engine when shifting. Check fluid level, level is fine, fluid is dark, dark brown & smelled burnt. Phone call to TCI, take the car to AAMCO, they are an authorized TCI outlet. Sent the car to AAMCO on a tow truck & followed. Car is dropped off & I wait for for 4 hours before someone gets to me & tells me the transmission was cooked due to low fluid. I called BS & showed pictures of the stick when I checked it. I wait for another hour, only to be told I would have to take it up with TCI. Another tow truck bill to have it hauled back to my place & a wasted day.

Next day, call to TCI & explain the previous day to CSR. I'm told to remove the transmission & ship it back to them on my dime so they can check it out for warranty purposes. Fast forward 2 weeks, I get a call from TCI & get the same story about low fluid causing the problem & that is not covered under warranty. Next day, I get my lawyer friend involved, sending them a "Letter of Demand" about refunding cost of transmission, cost of towing & cost of shipping. One month later, I get a check for the afore mentioned cost of the transmission "only". My lawyer buddy ended up taking them to court for the balance owed, TCI rep didn't show up, the judge awarded me the balance of the money, plus $1000.00 & TCI was ordered to pay court costs & my attorney fees. The lawyer filed a lien against TCI for the monies owed & to this day, I've never seen another cent from TOTAL CRAP INSIDE.
