*see my latest post* my torque convertor doesnt have lock up as some may remember, so i bought bowtie overdrives wiring kit to do this right. my trans is an 85 700 and has baout 10k on it right now, and its fluid is still pretty red but not too fragrant. it kinda stinks, but not too bad. i wouldnt know if this is normal but i have only smelled new and freakishly old 1963 "how is this car still running" fluid. no middle ground experience for me. im going to replace about 5 qts of fluid and the filter when i do these wires and am wondeing if i should put some kind of additive in it? its a decent but seemingly tired trans (maybe the gears)w/ 35s and 3.08. i know i know. within a few weeks i should have mannys 4.56 setup if he gets to work! lol just kidding. with the lockup functioning and new gears, would you think it will last and should i even bother with the additive? thanks in advance because trannys really are not in my book o knowledge yet.
