I was driving home and smelled tranny fluid burning so i checked the dipstick and it was reading norm/full...so i drove home and almost got to my destination and it started shifting hard and would come out of first just revs up..still goes into reverse but wont go out of first and shifting into either gear is hard.

SOURCE: transmission

Transmission model is 4L60E,and the symptoms you are describing is a common failure on these transmissions all the way back to it's predecesor,the 700 R 4 model.The reverse input shell,splines into the low/reverse planetary sun gear.The reverse input shell has a collar with splines made into it,and these splines are prone to stripping,and sometimes the collar itself will break free from the shell.Without the shell functioning,no reverse,and this is likely what you are hearing.Aftermarket companies sell heavy duty,and standard duty,replacements.Eventually,you will lose the forward gears also.Good luck.

1st thing to do is test the system for codes, the problem is most likely a failed or stuck shift solenoid indside the trans, have you ever serviced the trans, sometimes a fluid and filter cahnge will cure these kinds of issues.

SOURCE: transmission - no reverse

i had to put a new trans in my 2000 jimmy about a year ago there is something inside called a "reverse hub" its made from aluminum and not very hard to break..when mine broke i was stuck trying to move in reverse and it heard a pop then a winding down noise and sure enough its the reverse hub to fix it i just had the trans rebuilt

Sam,

I would start with a transmission fliud and filter service.

I would then have the trasnmission checked out by a transmission shop. The transmission most of the time has the direct drum band is starting to go. The shops can rebuild it no problem, This is a very common failure wiith the trasnmission.

Good Luck

If you have no reverse, more than likely, you have either a stripped or broken sunshell, assuming you have the 4L60E transmission. Are you absolutely sure you have all forward gears? Another indication of the sunshell being defective, will be no engine braking in manual second.
