So my transmission like to shift all the way into 3rd before I even hit 30MPH. Is this normal?

Not normal if you're accelerating hard enough, normal if you're not. It might also be shifting at an inappropriate speed if your axle ratios aren't a good match for your tire size. And if you are running big tires, have you recalibrated your speedometer? :)

Im running 31x10.50 with 3.73 gear ratio. Im not accelerating hard but even if I do accelerate hard the highest I have got to is like 40-45 and i'll be in 3rd. Never recalibrated to speedo but according to my gps im only off by 1mph. I know this Jeep has had its tranny swapped before.

Would it be necessary to have the computer flashed to reset it? Maybe when the trans was swapped it messed something up?

There is a cable that runs from your throttle to the trans to let the trans know how much gas you are giving it so it knows when to shift. Sounds like it is messed up.

32rh is a hydraulic transmission; i don't even think the computer knows it's there. Forget the speeds for a bit, what are the revs doing? Does it rev up above 3k before you really get moving? Does it shift from 2nd to 3rd at less than 1,500 and lug the engine?

It revs great. No engine lugging, shifts really smooth. Another thing I have noticed is it won't downshift much either. I have to pretty much come down below 10MPH before it will downshift.

That second cable connected to the throttle body bracket is what tells the transmission how hard you're stepping on the gas and if you have stepped down far enough to signal it to go into passing gear. Your cable might be set too loose. It is adjusted at the bracket on the throttle body after releasing its lock clip.

The cable is set to the point when at idle, the cable has no slack... it is just tight enough that it is not being pulled when the engine is at idle RPMs but it gets pulled when you give even a tiny amount of gas.

I had the same problem last year, check the cable up on the TB, the end broke off on mine was going straight from 1st to 3rd, the ends of the cable are made up of plastic so not very durable, i picked up a new one from the dealership for $50 or so

The white clip is very easily broken. Be very careful removing it and only spread it far enough to clear the locking tabs or you'll be buying a new one.

For your rig, unclip the connector off of the TB linkage. Hold the connector right beside it and adjust the housing after you pull the clip so that it is about 2-3 clicks too short. Be very cautious of how much you move the housing away from the TB. Too far drives the governor pressure up too high and creates hard shifts and isn't too great for the trans.

You can see the fine teeth under the white clip after you pull it. Each tooth is what I'm calling a click.

Ya, I adjusted the cable. It was ridiculous how much slack there was. Now the shifts are smooth and way better...although I do notice more gas being used lol but oh well!!

Taking the slack out of the TC cable shouldn't have had any effect on your mpg. :confused:
