well,i have had transmission trouble in the past, and for me, it is way to much work to do myself. and having "professionals" rebuild them twice, has resulted in nothing but problems with their rebuilds. now, at the first sign of transmission trouble, i get rid of the vehicle. it simply is not worth the hassle of having the transmission rebuilt, and rebuilt, and rebuilt. actually the best "fix" for an automatic transmission is what i did the last time i bought a vehicle. BUY A MANUAL TRANSMISSION MODEL!
