transmission issue?
 

my blazer runs but no drive.put in any gear and it acts like emergency break on but its not i put in nuetrel and it rolls but in gear no go motor bogs down like in gear what do i do?please help

Problem: Transmission goes into gear but feels very sluggish like the brakes are on, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time
Symptoms: Shift B solenoid failed. Or a wiring problem from PCM to Transmission... or PCM.
Possible repair: Easy fix in the pan


Does this describe your problem? If not, have you checked fluid level? After that it might be a broken internal part. If you do some searching there are a few threads regarding testing you can do before taking it to a shop.
