buy new transmission but don't understand gear ratios
hey everyone, after doing as much research as i can and talking to the few people i know that know some about the subject. i concluded that ill buy the same transmission i have in the truck now just rebuilt from a site. i have a 72 step side with a 250 and 3 speed floor shifter. the transmission is no good as it is and it seems to cost more to get it rebuilt. I'm not sure if its a muncie or saginaw but ill find out once we pull it out. after looking online for some time i finally found a site that sells both muncie and saginaw rebuilt 3 speeds but theres 5 different gear ratio options and i have no idea which would be the one i need. If anyone could help me understand this a bit more and recommend which would be best for a daily driver that would be awesome.
they start at 254-150 and go up to 351-189 heres the site I'm talking about if you can make sure this is the transmission ill even need because i see the site is strictly racing so I'm not %100 sure this is even what ill need http://www.smileysracing.com/shopping/?ic=1574 thanks a bunch |

Re: buy new transmission but don't understand gear ratios
The numbers they are giving you are the first and second gear ratio. So 1st is 2.54:1, second is 1.50:1, and 3rd will always be 1:1.
The higher number is a lower gear, so that 3.51:1 1st gear will be really low, and you'll need to shift out of first before you get moving very fast. That being said----those transmissions are stock units rebuilt for circle track racing. Its not the direction I would go. I can't imagine that you couldn't get your trans rebuilt cheaper with stock parts. The 3-speeds are pretty simple. Usually they need a couple of bearings, new synchros and seals. Whats going on with the trans you have?

Re: buy new transmission but don't understand gear ratios
That could be a clutch adjustment or other easy fix.
It is difficult for a shop to give a rebuilding price over the phone. This is because a lot of internal parts are reused on a Manual Transmission. Such as gears, shafts, etc... but if any of these are broke, worn, or missing (as in a trans brought into a shop in a box) then things can start adding up. I would maybe take the vehicle as is to a mechanic (not Goodyear or Meineke, etc...) for them to look at. A reputable Mechanic can determine if its a clutch issue or an internal transmission issue.
