i have a TKO and since day one until my car is almost at a complete stop will it let me put it in first.

Me too. Is this common problem?

i think it's tremecs trademark?

sometimes it will go into first before i can get it into second. what fluid are you guys running in yours? i think im gonna put some syncromesh in it monday and see what happens

preciousroy

well from looking at a few mags and such i think i have an old style tko, the new 500/600's have a 6 bolt shifter base in a perfect rectangle, mine has the front 2 closer together than the back 4. can anyone verify this? is a tko any good?

ya, those are very good trannys. i believe they were good to 375 lb/ft of torque

GM sycromesh is what Tremec recommends in their trannys. As for going into first...w/ a 3.27 first gear, you shouldn't be able to shift into 1st if you're going very fast.
