Yes. My trans is like this as well. I bought my truck with all the drivetrain installed and running. I changed out the TV cable and adapter on the carb to a BTO unit. There was a crappy $20 unit on there before that had a lot of flex. However, that did not solve the issue.

I put it in drive and step on it. It's a short shift for 1-2 and then again from 2-3. If I put it in OD right away, from a stop, it does the same thing, but it will hold 3rd gear until it's up higher in the RPM range. I don't know when it exactly shifts, I haven't paid attention to that.

simple adjustment of the downshift cable on the carb and she shifts perfectly
i added the FiTech EFI and the cables needed to be readjusted again so i took the truck by a transmission shop and talked the old timer/owner into adjusting it for me himself which he did, now the truck drives absolutely like it's a new truck. I am so happy to have finally reached the point where i can just drive the truck and not have to be planning out the next thing that needs done!

I can't do that with the set up I have. It uses a stock style TV cable and automatically adjusts itself.
