How to have the same rpm in high gear

I would consider changing the vehicle speed sensor. When they go bad, they can really throw out a lot of bad data to the computer, resulting in unexpected behavior like you're experiencing. They're only around $20-$25. I hope this helps! :)

Cars not control choke themselves electronically, this is likely the car trying to warm itself up quickly. The jerking will occurs anytime you shift into gear at an RPM over a low idle as the torque converter is being engaged. If the high idle last more than a couple of minutes then you might have an issue.

have you checked that the accelerator cable is moving freely, or that the carb slide is moving freely?

The RPM's are revolutions per minute. So when you step on the gas, the RPM's should rev high. Not going into gear is a safety feature,

Your reverse gear is the strongest single gear in your transmission it is not a high speed gear ut it s a high torque gear a if your car was heavily loaded or towing a trailer you wold require the higher torque for backing up

check and replace filter and fluids just like oil it tends to burn up and blacking and needs to be changed and flushed checking your tranny fluid it should be a red color not a dark red or with a black tint

Check the vacum lines going to the distributor and transmission. If they are leaking it could be your problem.

yes it sounds like you have no top gear/OD. run a trouble code test using the info at the link below.
