Ok this may be a dumb question but a mechanic(old school streetracer ) once told me i could use type f in place of dextron 3 to firm the shifts a little as it doesnt have the "slippery additve" for smooth clutch engagment, he said thats what B&M trick shift fluid was when it first came out. now I have to admit once upon a time i did this in my blazer a while ago when the tranny was a really really tired. and it did help, actually made it feel like i had put in a stage 1 sift kit almost. although a few months later the governer cap poped off and lost all my fluid while on the freeway basicly destroying my 700r4. but Im asking now because my th350 is acting tried and need to prolong its performance for a little longer since I have no money to work on it so im wondering if this is safe.
