Overdrive switch short

Ariana,

Welcome back. As far as the OD, if I recall, wasn't the torque converter rebuilt? Also, did you get codes specific to the switch or OD?

Also, please read through pic 1 below. I think you may find it of interest. Additionally, pic 2 shows the pressure regulating solenoids' location in the transmission. Since we know the fluid is clean and full and the filter is new, there shouldn't be any restrictions.

Let me know your thoughts.

Take care,

Joe

Hi Ariana,

The code is for the overdrive switch, as you know. Have you checked the fuse for the OD switch? It is fuse 13 in the central junction box.

If you have already done that and it is good and has power, move to the switch itself and check for power in and out.

I attached the wiring schematic below for you to reference. I highlighted the fuse and wiring to and from the switch, and then the wiring from the PCM to the control solenoids.

Let me know.

No, that would affect the overdrive only. It is very unlikely it would prevent the transmission from engaging.

Let me know.

Ariana,

Don't worry about a manual. I can get you the directions for removal/replacement, disassembly, and reassembly. However, it is an extensive job, and I would feel really bad to have you do it when it's a pressure-related issue. But it's your call. I wish we could check the pressure before you take it apart. Also, you may want to see if you can find a good used one with a warranty because you are going to be putting some money into parts. I just don't want to mislead you.

Let me know which direction you want to go. I'm here either way.

Take care,

Joe

That is a great idea, Ariana. Are you going to do it? Are you confident they won't leave you in the middle of the project?

I just spent an hour copying everything for the disassembly and reassembly of the transmission. I wanted you to have them. They are very extensive but relax. One step at a time and you'll be fine.

Let me know your thoughts.

Take care,

Ariana,

I feel the person that crossed the battery terminals should pay for it. I really feel there is nothing wrong with the transmission other than a pressure issue related to the pressure solenoid. But I can't confirm without the pressure test.

If they rebuilt the transmission, the parts they used never would have worn out to this degree as fast. As a result, replacing all the parts in the above directions seems over the top.

Have you tried pricing a rebuild kit? Is there any way you could get a different pressure tester?

I'm here to help, so let me know.

PS: Have a good weekend.

Hi,

I look forward to hearing from you. LOL A compression gauge won't work. That is likely why it is leaking. Did you ask around at parts stores to see if they would lend one to you? Also, the shop that offered to help you, would they lend one to you?

I attached the part number from the manual and found one online for you. I would feel really bad if you made the effort to find it didn't work. Ugh! I feel like I'm driving you crazy. LOL

Regardless, see if they will lend you a pressure tester. The part isn't really cheap, but you can likely find it for less than what I found.

Let me know and I hope you are enjoying the weekend.

Take care,

Joe
