Hi ,my ultramatic doesn't do so well up my big hill ,some times it will" downshift" in high range ,it drops down into its lower gear ,the rpm goes up and she climbs well,
but most of the time it just bogs down and I have to shift to the low range on the colomb to make it up
, it sounds from the threads that driving like this practice may be rough on the transmission
Down hills in low for engine braking ( a must as the drum brakes fade) it will rev up in low and then lock well

I've been thinking if getting a rebuild (70,000mi) vs a swap I've seen a lot of talk about a 727 in the threads I use my car as a daily driver which entails some time on the freeway .i try to keep it to 60 ,I know the speed limit in 52was45 mph
Will 60 blast the Packard 200 thunderbolt? The more modern trans fix this ?
I haven't found a local affordable person. To rebuild to ultramatic it sounds complex! I wonder if the average rebuilder would get the newances of the specifics like the o rings in the torque converter. transmissions by gene out here in nor cal was 3500 ,the ultramatic dynamic guy was2800 out in Virginia but I'm not sure if he's around
I have a selector shaft leak also which I fix with just adding fluid
I've added some b &m trick shift on recommendation of a post , I wonder if this screwed my shifting up by not using just some plain 10 wt or ATF
