Been looking at other options to put in my '85 K10 Burb (diesel) for a tranny--its got the 700r4/NP208 combo in it factory,and the tranny is losing overdrive and reverse after a good ride..time to fix it,or ditch it!. Was wondering if there is a chart that shows the overall length of different tranny/transfer case setups,or in other words,if there's any way to tell what other driveline combo's would fit without altering the driveshafts or crossmembers,etc.. I had a line on a TH350 someone got from a car (short tail) and bought a spacer for the tail end,they claim that'll allow it to bolt right in place of a 700r4 with no mods to the shafts or crossmember..that would suit me fine,I dont drive far and could care less about losing the overdrive or the slightly lower first gear the 700r4 has..but I'd be faced with the issue of getting vacuum for the modulator valve on the TH350,(I have a vacuum pump,but lack the VRV valve it would require)--also the torque converter will only have 3 bolts ,not 6,but still bolt up,the stall speed is slightly higher too,being from a gas engine.. So,anyone know what'll bolt up in place of a 700r4/NP208 without a bunch of headaches??..or should I bite the bullet and have the existing tranny fixed??..(I dont have much faith in the 700r4's to be truthful)..
