so i just replaced my neutral safety switch and now when i put it into gear it feels like its in third gear like the tcm is not hooked up. works fine in all gears except drive. i tried adjusting the nss and it did not work. tcm fuse is fine tcm is plugged in. not sure what i am missing. any help will be appreciated

ok just wondering could my tcm have gone out? everything is plugged in that i can see all the fuses are good thats the last thing i can think of

Why was nss replaced ?

carter442

i didnt have reverse lights as well as it would not start in park or neutral. so i removed it but cracked the case on removal. so i ended up buying a new one

was it still pluged in when it cracked maybe shorted something out ?

i honestly can not remember. but in drive it acts like the tcm is unplugged. my fuse is good when in 1/2 it will not shift to 2nd i double checked the harness connectors and cleaned them but still nothing

unplug tcm see if it shifts manually .

carter442

it will shift manually with it unplugged it acts the same no second and in drive its in like 3rd or something i really wonder if i fried it or if the nss needs to be adjusted for it

carter442

What i am experiencing feels like limp mode. So my question is has anyone experienced this after a sensor install?

i should have had this in the first post it is a 91 aw4. i unplugged the ecm and tcm and tried to reset it but still in limp mode

ok so i went out and really tested my jeep here are my findings.

with tcm plugged in- have manual first will shift to second manual third and then drive is od. does not always shift to first when slowing down if i am manual 1/2 so will start in second.

with tcm unplugged- no second gear in manual always first manual third and manual fourth.

can this because by a misadjusted nss? or is it a tcm problem?
