S10, 4 cyl, 4l60e. currently 290k.
Previous owner thought trans was bad and swapped it, same problem persist (hard 1-2 shift), his was done before 130k on unknown mile transmission
For probably last 50k, 1800 to 2000 rpm, it would go up and down in any gear
Last 10k, around 160*, whenever 1800 to 2300 rpm, it would have shudder/heavy misfire few time then downshift to keep rpm at 2500 rpm. It would start when transmission reaches 160* and higher.
I was told clutch band is likely going out
And the valve body for the 1800/2k rpm up and down.
If that's the case, any suggestion for improved/upgrade internals when I get the shop to rebuild it?
