(HELP) Chevrolet Tahoe hard shift from 1 to 2 gear! Bad Accumulator? TPS? Shift Solenoid?

This is starting to be an annoying issue especially when I have my family riding with me 😡. Also the transmission was flushed and replaced with new transmission fluid , rear differential oil done , the transmission was rebuilt in February of 2023. The rebuilt consist of remanufactured torque converter, new pump assembly, reconditioned transmission assembly, reconditioned valve body, new clutches, O rings, seals, new fluid and filter at the time, and a new rear main engine seal.

Hi I would check the transmission fluid level with the vehicle running on leveled ground if you haven't already. If no fluid is on the dip stick while the vehicle is running, you need to add more. If its good I recommend using a bottle of Lucas transmission stop slip. Just drain out a quart of transmission fluid and add the bottle of the stop slip.

Torque converter? Go to a transmission shop they sale a additive in a lil white tub stop shudder and it will work thousands of miles if that doesn’t work replace the solenoid
