High Cruising RPM

My 61 had 4.10 gears and 27 inch tires. 2800 stall. 3800 rpm at 65. Something is a miss.
 
700r4 with 3.27 rear and 28” tall tires....with lock up I can do 85 at 2500rpm. Sounds like you may have it in “D” not “OD” so it’s staying in 3rd. Verify by checking the indents. Should be Park/N/OD/D

Right, wasn’t sure how to show the (D).

Have you verified 100% that you actually have a 700? Just want to make sure we don’t overlook something simple. Google a photo of the 700r4 pan, it shouldn’t have any vacuum modulator deal on the back, and you should have been required to shorten your driveshaft.

Sorry too many things at one time. Yes have you physically verified you have a 200r4?

Based on your pressure readings I would say you are obviously loosing it somewhere whether it’s the pump or a seal in second gear has yet to be determined. If you put it into “2” and run it out then try to shift into “D” does it do anything?
