try atf+3 .. my syncro was toast.. i had no choice but to continue to drive it that way until i found more money.. it helped out a lot IMHO. Eventually my TO bearing crapped out and i tore the trans out and put in a 2000 cougar trans that i dropped a torsen in. Cheap fix.. but not permanent.. TH is really the way to go from my experiences.. but if you wanna keep driving it.. try the atf+3 or the MT90 mentioned above(i have on experience with it)
