Hello,

I was given a car whose reverse gear didn't work. Soon afterward, the drive gear failed as well. I did a transmission rebuilt on it and now the reverse gear works perfectly.

The drive gear though is not working. The car can go forward when I switch to drive, but no matter how much I depress the gas pedal, only the engine roars, but the car can only go up to about 20-30 mph; it is almost like the car can't switch gears automatically.

While I can't say the rebuilt was flawless, I am pretty confident about it. Could there be other problems causing this? I noticed that when switch gears with the shift stick, the switch was not immediately and I often had to shake it back and forth a little before it would change the gear.

If the transmission rebuilt was flawed, where do you think the problem most likely is?

Thank you for your time.

Jack

P.S. I know the car is old and has high mileage, so it is probably not worth it to fix it. But it was free and I want to get more experience working with the transmission.

Hi skswbwt,

Seems the gearshift cable needs some adjustment. You are not getting the correct signal when manually shifting.

Does manual shifting works in all the gears?

Hello,

Thank you for the response.

The car is an automatic. When I shift gears, only a change to Drive causes problems. Say when I shift from Park to Drive, I have to rock the shift stick a little before change would be made.

Can you provide some instructions (perhaps a link?) On how to adjust the gearshift cable?

Thank you very much!

Jack

Hi skswbwt,

You need to confirm if the cable is worn first.

You can do it and at the same time check or sdjust the cable.

Remove the centre console.

You would see the gearshift cable comig out in front and goes into the floorboard. There is a joint with a spring clip and 10 mm hex jam nut.

Pull the spring clip out and see if the hole is in alignment between the cable and the housing.

If not in alignment, loosen jam nut and adjust accordingly. You need to be in Park position to be able to get a correct reading.

Try pushing and pulling the cable to see if there is a lot of free, if there is, you need to check the cable end at transmission, it could be worn or a bush is missing.
