93beast

i have a 93 firebird with the d10 shift cable, not electronic. Its been really weird with the shift points. At first we thought it was the cable until we adjusted it and kept doing this thing where it shifts into a gear and then bogs down and i have to hit the gas to clear it, sometimes it wont clear. If i shift it manually it runs fine, but when it's in Drive it does this. It usually does it in 3rd gear or OD. If you have any idea what this is please let me know.
