[me and my metro]

I have a 700r4 in my 84 GMC Diesel pickup with 4.56 gears and 33" tires. This combination works great, the gear splits are perfect for towing or running solo.
I also have a 95 Ford chassis motorhome with a 460 and an E4od and 5.13 gears. The gear splits in the E4od are not ideal. Lock up torque converter timing adds to the problem. One two is fine especially with the 5.13 final. Two three is too big a split at about 1500 rpm, plus immediate torque converter lock after shift. Three four is great, about 1000 rpm. For about $2000. someone makes a valve body and programmer that adds two gears. It uses overdrive in between each gear for a total of 6 gear ratios. If I drove this more often I would consider this.
