I was mistaken...the AOD-E RWD Tranny was replaced by a front FWD transaxle in 99. so you should have a CD4E transaxle.
The NSS (also called the manual lever position switch)should be on the same side of the trans as the linkage.....the linkage should attach to the drive position selector shaft...and the MLPS slides onto the drive position selector shaft that protrudes out of the side of the transmission..
check out this picture on ebay...search item #170418763479

BUT BEFORE YOU DO THAT....

check the alarm issue.....try turning the alarm off and on a number of times....

did you change the alarm wiring in any way? does it have a starter kill relay that you might have disturbed??

 

it is under some coolant hoses on top of the trans. the linkage does not attach to it on a cd4e. on a cd4e the liknage goes above the left side axel. the mlp just reads internal trans off of the rooster comb in the trans.

 

Yes we replaced MLP switch from transmission we took out did not
make any difference. You mentioned turn security alarm off and on repeatedly is this done by turning switch on and off.I am not sure
about the starter kill relay is it built into security system.Thanks

 

what can you do to make it start???

 

Short out solenoid to starter with switch on spray gas into intake will run till gas that is sprayed into intake is used. Will not turn over by switch Thanks

 

Does the code have to be reprogramed after installing a different trans
I have received different anwsers on this .

 

what code are you talking about?????

 

Reprogram to accept the new part. Changing the transmission could that
effect the security system.Thanks

 

no that wont. seems like either for some odd reason you lost your pats program (keys) or something is not connected. maybe a poor ground. really hard to say

 

try swapping the starter reley and starter reley diode and see what happens. when you turn the key on dpes the theft light come on and go off or does it flash or does it come on and not go off??
