4 spd auto with lock up converter

[RGT]

I recently installed a Bow Tie Overdrive's 200R4 transmission in my '71 C10, really like it so far. I also took off the old headers and installed factory manifolds. I can actually hear the radio on the highway now. It's nice that the right holes were already in the frame for the crossmember to relocate to and that the driveshaft did not need to be changed. I do find that around town I have to keep the transmission in the 3 position instead of the D/OD position or it wants to shift into OD at too low a speed.
