Hi All,
I haven't been very active in the past few years but I'm proud to say I've had my Nomad for nearly 20 years! bought an original CA car in Long Beach CA, moved it to the San Francisco bay area, then to Salt Lake City, to San Antonio and now in Spring Tx(Houston) love the car and it will be the last one to go if I ever sell it!

I recently replace my original 2Bbl Carb/manifold with an original 4Bbl Carb/manifold but I need to adjust the trans shift points as it now shifts from 1st to 2nd at about 30mph. Im assuming the adjustments are on the linkage at the side of the carb but looking for advice on how to get it right.

Thanks in advance for your help!

Trial and error. If it shifts too soon shorten the linkage a couple of turns (screw the pivot back on the rod). If it shifts too late lengthen the linkage. Test drive and adjust until you’re happy.

Find an "old" Motors Auto Repair Manual; they have the procedure for adjusting shift point linkage on the Powerglide equipped cars. Mines a 1959 edition, and starting to come apart at the spine.

It's been a very long time (almost 60 years), but I had a '60 Chevy with a powerglide, 283, and 4 barrel. I never found an auto shift point I liked. It was easier (for me) to simply 'manually' shift between 'D' and 'L' (the only gears available). I was better at 'timing' my secondaries' opening with my gear shifts (up or down). I basically drove the car like a '2 on the tree' but w/o a clutch. I even installed a tach

The transmission was durable, but I can't say I liked it.

Just info.

Pete
