Technical Swapping out th350 for a 700r4 in a 1951 chevy

2004R has a .67 overdrive,700r4 has a .70

 

I loved the 700r4 I had built for my '49 truck , loved it . Had around $1500.00 in it with a corvette converter and a TCI constant preasure valve body to eliminate burning it up due to tv cable not being 100% right . Had the B&M adjustable lock up control but when it went out I just powered it straight (still through the brake pedal switch) and worked great , never had to drive around town with shifter in Drive . I could feel it shift into all lower gears and then into overdrive , Then felt the converter lock up - almost felt like another gear ! I had tosell my next project due to health but it was a '38 chevy and I already had my 2004r lined up ready to go . Loved my overdrive !!!
