Going on three days of stuck on a confounding problem. I hope tomorrow will not be like today and the day before rolling around in transmission fluid scratching my head in desperate, hopeless, pitiful agony hoping to the heavens above I at least figure out what's causing my car's problems. (1991 740 turbo wagon 4 cyl)
Car will move forward only. Park works. Neutral, I get forward. Reverse, I get forward. The shifter knob only goes as far down as 2, it will not go to 1. PRND21.
I had the lower valve body out of the transmission to replace the kickdown cable, and I might have moved the gear selector by hand I do not recall I've been under this car going on 9 weeks straight fixing various problems I inherited from the previous owner.
I can't understand how my shift linkage could be misaligned, as the car only starts when the shifter knob indicates P or N. So, I must be in P and N at those times, which means the linkage has to be synced correctly? Right?
I put the valve body back correctly absolutely I made diagrams of all my work, believe me I try to be very particular and organized.

I don't know what the solution is, but I'm not clear if you've read the FAQ re transmission linkage?
From what you've described, it seems like the linkage is messed up. There are a lot of parts *inside* the trans but not outside, so there are probably a limited number of ways to mess it up.
For example, my transmission mount was worn out and it made the lever hard to shift out and in of Park. Simply replacing mount fixed my problem.
Also, we can't see your photo on other forum without being members.

I did not know about the photo thing. I could not figure out how to get a
photo with my reply on this site. I have given up on the car because I know
my linkage is absolutely fine i can just look and tell i still have the
trans pan down and anyone can see the linkage is in park just fine.

What a drag re car! You're probably on a shoe string budget? I would guess repair a transmission shop would be $250-$350. Plus there will be cost for tow to repair shop. My kick-down cable replacement cost $275 which included new fluid and 1-year warranty.
For photos go to "Brick Pix" then in that window go to "Add A New Exhibit" (below "Donate" button) then fill in empty fields in that window. The new photo/exhibit generates a link path in box from where it can be copied and pasted into your post. Mmmm, I can see why people don't post too many photos! Tip, you don't actually have to worry about photo size, but do use guidelines because giant photos are hard to see and bog down page display.

It sounds like the shifter inside the car is not properly synchronized with the lever that actually moves the valve body inside the transmission. Thus, when the inside shift lever is in "P", the transmission is actually in "N", when lever is in "R" the transmission is actually in "D", "N" is "2", "D" is "1", and "2" is pushing hard against the stop. Which is why the lever won't go into "1".
The parking pin is inside the transmission, and is what locks the transmission output shaft and stops the car from rolling away when you park it. One way you can test it is to put your shift lever in "P" and see if you can roll the car (hand brake off). If the car moves more than an inch or two, like it would roll down the street, then that further supports the idea that the lever and the transmission are not matching up, and that the car is really in "N".
I have not actually disassembled this part on an automatic, (my 850 is automatic, I haven't touched it on my 945, and my 245 is manual) so I can't offer details of how to check the linkage, but since that's what you had apart, I would re-inspect that for possible ways that it could have been reassembled too-short or too-long or misaligned or something.
Good luck!

I tried desperately to push the car forward in P but now I am certain it is in park. I have not one doubt.
I have tried time and again to think of how I could have moved one thing and disturbed something.
I attached a picture of the gear thing with teeth inside the transmission, and it seems as though it (the rectangular shaped plate thing with an opening down it that clamps into the "teeth" of the gear selector thing) is in fact in park.
The first tooth groove is considerably deeper than the rest grooves, so I don't know what that means. . ...
I am lost completely now.

When you say that park works, have you actually checked to see that the parking pin locks the transmission in place?

I am at least 80 % certain it is in park because when I rev the motor in park it does not go forward. Any other gear and it goes forward when revved

I have never seen the parking pin in one of these transmissions. However, the parking pin is what engages to keep the car from rolling when it is in park. I suspect that what you think is park may actually be neutral. Have you tried rolling the car when it is in park? If it rolls more than a foot or so, it is not in park.
If, in park, the car is actually in neutral, it would make sense. The next position would be drive, followed by 2, and then by 1. No reverse because it is on the other side of neutral.
I, unfortunately, don't know enough about these transmissions to tell you where the "out of whack" may have happened. Sorry!

Okay I now understand what you all are saying about the switch. Okay, let me look beyond that now. . . ...
@Budweiser dude: where exactly is this parking pin and what does it look like?
is it only visible when the trans pan is off? Right now the pan is off because I wanted to get a look at the gear thing inside.
Also, when you say my linkage can be "out of whack", I have never actually been given a good explanation as to what this means and how it can become so -- like to give one?

I have almost no experience with 740's. However, in the 240's, the neutral safety switch is in the shifter, not in the transmission. If 740's are the same, your linkage could be out of whack. Beyond this, I'm afraid I'm little help.

The fact that it starts in P and N proves nothing about the trans - the safety switch is on the linkage, not the valve body.
I'm no expert on auto transmissions, but I've had a few apart, and my thinking is that the spool valve moved by the selector cross shaft, is not aligned or synched. As you had the valve body off, that's the likely cause.
I can't recall exactly but there is a small link between the cross shaft and one end of the spool valve? I'd start there.

@Rhys: I appreciate your response very much, but I will need some clarity.
Okay, disregard the NS switch, I understand that part now. ..
If you can tell me more about this "spool valve" and selector cross shaft, I can give a better response.
What does the "spool valve" look like, where is it located?
What does the selector cross shaft look like, where is it located?
I am bad with terminology but if you tell me describe it or what not I can give a better answer thanks a lot

The valve body has cylindrical valves in it - hence it's name - and you can see them oriented front to back. One of them is controlled by the shift lever, and that mechanical linkage starts at the lever on the shaft that the rod from the shift lever (under the car) attaches too. Follow that shaft through the trans - the other end has the bell crank you attached the cable to ( as I recall). That shaft also controls a rod that runs to the rear and applies the pawl that acts as the parking brake.
What might be at fault here is the connection between the shaft and the "manual" spool valve. Operate the lever on the shaft with the link from the shifter disconnected at the trans end. Observe the movement in the trans and you'll see. Staring at all those parts while stationary isn't going to help you understand it.
