When the car drives it wont shift down. When you put your foot on the gas, like it slips when it wants to change but then doesn't change it goes back to the original gear.

Good morning,

There is an adjustment for the downshift cable for this issue.

I attached the procedure and a couple pictures for you to view.

SHIFT CABLE

1. With engine static, remove console.
2. Move selector lever to D, then remove lock pin from cable adjuster, Fig. 1.
3. Ensure hole in adjuster is aligned with hole in shift cable. If holes are not aligned, loosen shift cable locknuts and adjust cable as required.
4. Tighten locknuts and install lock pin through adjuster and cable. If lock pin binds during installation, adjustment is incorrect.
5. Check transaxle operation in all shifter positions.

THROTTLE CABLE BRACKET

1. Disconnect throttle control cable from bracket and control lever on transaxle.
2. Bend down tabs on locking plate and loosen bracket retaining bolts, Fig. 2.
3. Position adjusting tool between bracket and throttle control lever as shown in Fig. 2. Tool 07974-6890300 is designed to provide 83.5 mm (3.287 inches) clearance between throttle control lever and cable bracket when tool is installed as shown in Fig. 2.
4. Position bracket so that there is no binding between bracket and adjusting tool, then tighten retaining bolts while holding position of bracket.
5. Remove adjusting tool and bend locking tabs against retaining bolt heads.

THROTTLE CONTROL CABLE

Prior to adjusting throttle control cable, ensure accelerator cable, carburetor idle speed and control cable are properly adjusted.
