BW35 Troubleshooting 140-160 1970

Everyone,

Working on a 145 w/ a BW35 transmission and I am having some trouble. Primary issue is under light acceleration from a stop...I am getting a lot of hesitation/stumbling at low speeds/RPM and then it feels like something "catches" and the car takes off. The transmission is the most recent change (car was previously a manual), which is why I am suspecting it. Fluid level appears correct (although the dipstick is very difficult to get a clear reading on). Shifts are nice and smooth and once at speed/revved up everything is smooth. Anyone else previously had this issue? Any other items I can check? Transmission was previously rebuilt only a few thousand miles ago (from an 1800) and looked great before installation. I am running Castrol Type F fluid.

As far as stage 0 items, I have triple checked the mixture/timing and the carbs have recently been rebuilt and ran great for several thousand miles. Also everything runs as expected when there is no load on the engine (i.e. in park or neutral) and I see the timing advance as expected when watching with a timing light. Plugs are fresh with correct gap.

Thanks,
Brian
