4x4 727 rebuild or replace?
This is for my 71 4x4 that is going to have a 451 in front and big tires behide it. Right now it is making a kinda whining sound in first but i was planing to do something with it anyway. Should i get a 727 from tci or other places like that or just rebuild the thing myself? I plan on getting the books and videos for this as i have to rebuild one for a 1/2 ton. Goin to be a good practice run before i rip into mine.
Where is a good place to get the rebuild parts from? Also what torque converter should i get? Its goin to have the 451 powering it and a final ratio of about 100-1 with 40 inch tires. Thanks |

well, all my 727's wine in first, some worse than others, never seemed to go out though.
first off, big tires and 451 inches, is this a mud buggy/hunting rig, or a mud slinger??? TCI is a good place to get kits. |

Im going to have to make a new tunnel anyway as im going to raise the engine and trans up 3 inches to clear the new front axle and keep the tcase off the rocks. So ill probably make the area surrounding the 727 out of 12 or 16ga to keep chunks of metal out of my feet incase the trans blows up. I dont know im just prepairing for the warm weather to come so i can get this prodject going. Might just go with a manual trans so i dont have to worry about this kind of stuff. |

with gears like that (double t case?) the hard shift is not necessary, but a quik reverse/foward is, you can tell your tranny builder that, or do some reaserch, my bud does all our trannys, so i really dont know. 4 speeds are nice, untill you get the clutch hot or wet, also, they are harder to rock, and harder on the running gear. wich axles are you running? do you already have the tires? |

sorry for the delay i forgot about this thread. Would a manual valve body be harder on the 727 in an offroad situation? Iv got a set of rockwell axles that have 6.72 gears and goin to run 48" tall millitary tires.

Can't use a manual since it does not hold the over running clutch in low gear. Good way to explode a tranny.

There are manual valve bodies that do apply the rear band, they're available from the more technologically advanced companies.
