Gear lube is to thick for the neon trans. That sounds like a shifter, or shift linkage issue. Shifting the trans while out of the car will do nothing to it. It really really sounds like the cable needs adjusted.

The Castrol Gear Oil is the same viscosity as the Mopar MTX fluid. 75W-90.
I found out that Mopar fluid is GL-5 rated and Castrol exceeds that rating.
I also found out that the Mopar fluid is full synthetic, and so is the Castrol.
Therefore, I doubt the fluid is the problem. While I am at it, I will check the linkages to see what adjustments I can make. If that is all it is, Wonderful! But I would still like to know what position the tranny is in for gears 1-5 and reverse with the Crossover position defined as well just to be on the sure side.
The damn battery box, PCM, and other wires make it hard to view it without removing it, otherwise it would take someone about 1 minute to tell me.
When I went in to adjust the crossover cable as suggested, I removed the cover and found that the crossover bushing had popped off the connector pin on the shifter! YEA!!!!!! WOOOOHOOOO!!!! Simple problem!!!!!
So, I popped it back on, loosened the bolt, did the adjustment per the book, and drove that sucker all over the neighboorhood!
Just as I said, weird problem. My best guess is that it was just about on the verge of popping off when and I put it into reverse to get it out of my garage, it went into reverse THEN come off the rest of the way. I checked it out, and the bushing looked to be OK, so who knows how long it had been that way.
The gear oil is not likely your issue. I used AMSoil 75w 90 for over a year (street and racing) and no issues with either trans. Sold my 3.55 for 3.94.

just a thought i have a honda 5 speed when i rebult it cause 5th gear went i put in that type gear oil and the tranny seized up i read that the gear oil was to heavy a weight. might want to ask dealer what weight to use.
The Problem is solved. It was a disconnected cross-over cable at the shifter.
We no longer have any problems here guys! I found the problem. The crossover cable got disconnected at the shifter. Once I connected it, life was good. I am driving the car and do not have any problems at all.
It is strange that the cable popped off just after I backed out of the garage, and at some point I may need to replace the bushing (if it ever pops off again) but since I never checked it since I have had it, who knows how long it was like that.
But, this is a good post for someone who may have a similar problem down the road. Car not going into the proper gear? No reverse or proper 1st gear? Check to see if the crossover cable is connected at the shifter. If disconnected, check the bushing to see if it needs replacing and reconnect when ready/replaced. Problem solved.
