what do you mean by it won’t see the d position
do you mean you can’t drive it in that or do you mean it will be like the Tcm isn’t there because I just put a tcm in and before that you had to press the gas down a good bit for it to move and the whole point of me doing that is so the d dosent do that when driving.
So will it be like there’s no tcm or will it think it’s in a different gear and not shift right or will it just act funny

 

what he means, is, if you start your jeep, and put the shifter into D, then when you step on the gas, it will be very slouchy, and not want to go anywhere fast.
what you would need to do, is just select 1-2, then you can take off like normal, then shift up to 3, then D. but since 1-2 is shared, you will lose second gear, so you will have to rev it up in 1-2 before you shift to 3.
not much of a big deal, i did it for a couple years this way till i figured out my problem.

cheers.
