Welcome to 2CarPros.

Here are the directions specific to your vehicle regarding the shift solenoids. The directions are broken into two sections, the 1-2 solenoid and 2-3. All attached pics correlate with the directions. Also, to access the solenoids, you have to remove the side cover from the transmission. Those directions are first. Note: The cover removal directions are for cover replacement. You will not be replacing the cover, just following the directions for removal and install.

1-2 SHIFT SOLENOID VALVE REPLACEMENT
1-2 Shift Solenoid Valve Replacement

Removal Procedure

Important: Retainer clips hold in each of the valve line-ups. Use a small screwdriver in order to remove the retainer clips. Be careful not to score the valve body when removing the retainer clips and valves. Before removing the valve line-ups, inspect each valve line-up for freedom of movement.

See pic 14

1. Remove the transmission side cover. Refer to Control Valve Body Cover Replacement (See: Valve Body, A/T > Removal and Replacement > Control Valve Body Cover Replacement).
2. Remove the 1-2 shift solenoid retainer clip (304), the 1-2 shift solenoid (305) with O-ring (303), the 1-2 shift valve (302), and the 1-2 shift valve spring (301).

Installation Procedure

See Pic 15

1. Install the 1-2 shift valve spring (301), the 1-2 shift valve (302), the 1-2 shift solenoid (305) with O-ring (303) and the 1-2 shift solenoid retainer clip (304).
2. Install the transmission side cover. Refer to Control Valve Body Cover Replacement (See: Valve Body, A/T > Removal and Replacement > Control Valve Body Cover Replacement).

Important: It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

3. Reset the TAP values. Refer to Transmission Adaptive Functions (See: Automatic Transmission/Transaxle > Components > Transmission Adaptive Functions).

Real quick. When I put the new solenoids in which way does the clip go? From the bottom pushed to the top, from the top pushed to bottom or from the sides?

LOL they go from the top down. A very easy thing to miss. Take a look at the last picture I posted above.

Welcome back:

Interesting. Are you able to get reverse at all? Let me know. Also, I noted that you attached pics of the shift cable. Here are the directions for adjustment. The attached picture correlates with the directions.

_____________________________

4T45-E - AUTOMATIC TRANSMISSION
Shift Control Cable Adjustment

1. Place the shift control lever in the PARK position.

See pic 1

2. Carefully remove the shift cable end (3) from the transmission range select lever (5).
3. Release the shift cable retainer (3) from the shift cable bracket (6).
4. On the underside of the cable adjustment lock protective sleeve (4), release the retaining tab using a flat bladed tool.
5. Slide the cable adjustment lock protective sleeve (4) toward the end of the cable (3) to expose the cable adjustment lock (2).
6. Release the cable adjustment lock (2) to allow freedom of movement of the cable end (3).
7. Secure the shift cable retainer (3) to the shift cable bracket (6).
8. Secure the shift cable end (3) to the transmission range select lever (5).
9. Insure both the shift control lever and the transmission range select lever (5) are in the park position.
10. Depress the cable adjustment lock (2) to secure the adjustment of the shift cable end (3).
11. Slide the cable adjustment lock protective sleeve (4) over the cable adjustment lock (2).
12. Test the shift control lever in all positions for proper gear range selection.

Let me know if that is what was needed or what exactly is happening as far as can you get reverse, park, and neutral in different shift positions.

Joe

So today I messed around with the shift linkage then started the car and it went in reverse and felt like it was going to go in reverse so I got out the car and shut the hood and went to put it in reverse again and it didn't go anywhere. Does it matter if the bracket in the first picture isn't bolted on or does it have to be. When I have it in park does the neutral safety switch have to be all the way to the left like the second turpitude? Do I need to do anything with the adjuster or whatever it's called in the first picture I just uploaded?

So I don't need to mess with label (1) at all? And label (2) (3) and (4) are all together already. I loosened the bolt and moved the Transmission range sensor all the way to my left. Is that right? Do the 2 bolts that hold the transmission range sensor on the transmission have to be all the way tightened? Like if the back 1 isn't all the way tight would that make it not go in reverse?

Welcome back:

The bracket is what enables the cable to move the shift lever. If that isn't bolted on, the transmission will not shift or at least not shift properly. Bolt that on and let me know what happens.

No sir. Okay, so mostly all of the transmission side cover bolts were 10mm but maybe 2 or 3 were 13mm so I need to know if the bracket goes on top of the transmission where the 1st 13mm bolt is on top closet to you if you were looking up under the hood (front of the car) and what else could I be doing wrong? Or not getting right? 1 more question so when I did take the side cover off a lot of transmission fluid leaked out. I do not know if all of it did or not so I only put a total of 5 quarts back in (my car manual says 7 qts) could the fluid be too low?

The brake lights work I have the neutral safety switch bolted on the transmission with the lever and shift cable attached at what I think is the right position (shift linkage bracket bolted down too) when I didn't bolt the bracket down u barley had to press the gear shift meaning it was very easy to move from P to R, N, D and with bracket bolted on to transmission it feels like normal shift. It just doesn't go anywhere in R, N, D, etc.

Look at the pictures I honestly don't know what could possibly on wrong, or can having too much transmission fluid or not enough make it not go anywhere.

Not enough could cause it not to move, but if you put 5 quarts in it, it should move. Are you certain everything in the trans is plugged in?
