Answer me this.. why when I dropped my pan for the first time I didnt notice it for cpl days but when I dropped the lower valve body there was no manifold pressure switch bolted to the valve body....?

Here is the lower control valve assembly, I assume this is what you are speaking of.   This is a 96 manual, the 05 might be different, I don't know of a manifold pressure switch

Are these numbers off for the PC solenoid? Normal not normal ? Solenoid bad or good?

Ill post the info on the pressure control solenoid.  If you disconnect the main plug you can test the resistance of each solenoid.  There is an extensive analysis of the pressure control solenoid

But I don't get it how was my car working the while time I had it if there was never one . I dont see how I'm just lost on this one

Not sure, but maybe you missed it?  As it shows a part number you have one.  If I were you I would order this

No I didnt miss it . Its bolted to the lower valve body supposedly there was nothin there. 

It makes no sense that it wasn't there and it still ran.  I can't help you with the 05.  If I can get to the library tomorrow Ill print out the lower control valve assembly for you

I gotta run obd again idr if live data tap numbers I got was when idling or not. But they shouldn't be red. Whatever is makin my pressure system off and my engine torque is negative and or very very low.  Its somethin to do w that. I'm tryin yo think what would cause those two

Show me the negative engine torque numbers if you can so I can see the category and look it up.

I dont have a screenshot of that. But I do remember it sayin engine torque and it was negative and when i would give it gas it would go positive but not high at all numbers stayed below 18 when it went positive. Pretty sure it was transaxle

Under normal conditions in snowy conditions, if the front wheels spun, the front brakes would pulse to stop wheel spin, if the brakes couldnt slow the spin, the torque management system would drop cylinders.  Does the engine stumble going weakly through the gears on the lift?

Do me a big favor and send me the model number of your code reader, I want to know that it can retrieve Body-B, Chassis-C codes.    We already established that you have NO Powertrain-P codes.

And make the trans very weak to wanna engage.. torque converter? A busted seal? I dont see any leaks. Differential? Loose drive chain ? 

My gut is this is related to the torque converter or pump.   The symptoms for a loss of drive along with a loss of reverse don't converge, unless its related to pump pressure.   The problem impacts F and R.   

I believe you have a transmission control module (TCM) and we need to look into that.  

Explain the manual shift cable are you sure you have it adjusted correctly?, when it is each gear, can your reader confirm that the manual selection is the actual selection?  What made you pull the pins as you said?

It's the autel ht200. Wifi one. And I dont really remember ik I mess w alot of stuff under the hood and car unplug connectors and sensors but I'm pretty sure I've always ran my obd when I got everything back together in order not to get codes. But sometimes I ran obd and I'd get the most random codes in the world with stuff I didnt even mess with . No engine is perfectly fine idles great starts great. Brand new battery but for some reason my battery terminals get corroded fast and it slooooowly drops charge not lose charge but drops to like 11.7-11.9 and yes my traction control works

Use felt terminal protectors. These are impregnated with a corrosion inhibitor. They’re fairly popular because they prevent corrosion without the mess of sprays or gels. NAPA has them and they are inexpensive.

The system uses about 50 ma of power when it shuts down (door lock signal, remote start signal, alarm) and the battery will go dead over a 2 week period if its not charged by driving, or only driven short distances, especially in the cold months.  A trickle battery minder is a good idea, especially since you aren't really driving the car.

See I thought the shift cable could be adjusted what I didnt know was don't try adjusting it if everything is matching and it dont need to be adjusted. Lol. I believe you're right also it's got to do with the pump or converter it's one of those two whining and luckily I have a brand new secondary pump on deck. Could be broke gear could be broke shaft . Yea I have a tcm and as far I know it works.. I've tested pretty much every wire harness under that hood and on that car multimeter and test light. But some ground connections are stronger than others some light up green as bob Marley rippin one and some are barely noticeable faint green some dont even light up but few. Same with red powers .
