Just installed my 4T65E in my n/a 2000 bonneville se. Got it all installed, on the transmission side cover it says rebuilt, the coolant lines had flared fittings and the quick release ones on my old ones with the check valve was a totally different size, so found a adapter and drilled it out to match line size. Solved that.

However, my car wont start. I noticed the orange light on the dash thats behind my p, r, n, d, 3, 2, 1 isn't lit. So I'm guessing its saying its in gear. The orange on the shifter by the shift boot is right on the money in every gear. So I went back with a buddy and triple checked everything and we really didn't unhook anything except the main wiring plug. I called the builder back and he said the neutral safety unit is bad. I said it was fine before and i said I think its inside the trans and he said no its bolted to the outside of the tranny. I know on the 4t60e'* its right on the shifting linkage, but i have a cable on top of mine thats it, so I'm not sure what to do, I have no power going to the purple starter trigger wire.

I for now, ran a jumper from the purple trigger into the car that i can just stick in the cigerette lighter to trigger the starter, yea kinda ghetto but u gotta get home 80 miles from the shop its the only way. My reverse lights work and tranny seems to shift just fine.

I was thinking it needs maybe a security reset, but when i turn the key forward and roll it into start and back to acc the security light stays off... So any ideas? Will a 1997 4t65e work in my car?

Sounds like the neutral safety is out of adjustment. If not in park of neutral it wont allow a start. The switch is on top the trans right where the linkage connects. Loosen the bolts and you can adjust it a bit.

Try holding the key to the START position and pull the shift lever from P all the way down to 1 and see if anything happens.

I talked to him on the phone. Sounds like he has nothing what so ever. Makes me wonder if it'* the wrong transmission. Or a bad wiring harness.

Wrong transmission, basically the guy admitted i could be stuck in a half year where the 97 he sent me had a neutral park safety on top the of tranny and my car had a build in one, so its not sensing that I'm in neutral, so I ran a trigger wire to the starter purple wire to a push button and mounted it under on my steering column cover. I guess I will have to roll like that for a while. I know its eliminates the safety, but he wants me to pull the tranny and send him my original and he will send me mine back rebuilt, but I really can't cuz i don't have another vehicle and I work 2 full times jobs and get 3 hours of sleep and that kills me and have no way to get to work with a week of down time:(. Is there a wire that goes into the trans that I can just run a jumper wire to and somehow reduce the voltage to it to 5 volts and it will make the pcm appear its in neutral so i can just go back to my turn key start?

How does a guy reduce a 12v source wire to a 5 volt? will a in wire resister work? Not sure how else to turn 12 volts into 5.>>???

If you could figure out which wire is which on the harness, couldn't you just cut them, connect them together and bypass the neutral switch?

you can switch from a internal pnp to external

That requires dropping the cradle though and i'm not gonna do that unless i'm gonna replace it.. I talked to the guy who sold it to me and finally came upon a agreement with him. He'* gonna take my old tranny and rebuild it. and ship it back to me. Now I do want to do a shift kit, thrasher? zzperformance? not sure yet. Need opinions cuz i'm ordering one in a few hours.

Build your own shift kit, you can use washers if you want. No difference.
