Overdrive light flashes and when driving feels the gears slip. Car doesn’t move and rmp's just rev high if you accelerate but car doesn’t move.

Hi Kendrick,

The fact that you have a hole in the transmission is a new one on me. Depending on where this hole is, you could have lost your transmission fluid which would explain why it won't engage a gear and move. Without fluid the transmission can't function.

Can you give more detail on where this hole is or even get us a picture of it? Then check your fluid and see if there is any in there and what condition it is in. Thanks

The transmission was not leaking, still held fluid in. But I’m not to sure if the transmission would lose pressure or something that would cause my over drive light to flash/blink and feel like the transmission would slip into gears.

I can't say that I have ever seen a hole like that. Does it go through to the outside? Meaning if you had the pan on it could you put your finger inside? Are the edges sharp like something has punctured it?

Either way, if it holds fluid then I would not think this hole is causing your slipping issue. The transmission itself is not under pressure. Your oil passages and things are what are under pressure.

That leads us to needing to know what codes are in the computer. One this vehicle they are going to be pretty basic but they will at least point us to a solenoid issue or a mechanical issue.

I suspect you are going to have an internal issue that will require a rebuild and in this case, it may be a good idea to just replace the unit with a reman unit. That way, you take care of that hole as well.

I attached the transmission code descriptions for when you pull them. Let me know what you find and we can go from there. Thanks

1. I wouldn’t know how to check the codes, not sure if paperclip method works the same for check engine light.
2. I can run the vehicles since the pan is off and no fluid is in currently.
3. Do you know if Toyota dealer ships can run the codes on my car since it’s a 1993?

Also it is sharp from around the edges. I can’t see the hole from outside but if I run my finger down the whole through inside fluids start to drain down my finger.

Yes. It should. You will see in the attachment I gave you in the prior post, that the code number is set up the same as the engine, two digit code. Here is a video to pull the code. Worst case, a dealer can definitely do it.

I would pull codes before going any further because I would hate to do a rebuild or replace it, if it is just a solenoid or an easier repair (I doubt it, but I have been burned to many times to not start with the basics).

Based on the second reply. I would start sourcing another unit. You may want to check with a dealer to cover your bases, but I have never seen a transmission with a hole in the side of the case like that. Even if you figure out the issue, you are still going to need to replace due to that hole. I would not try to patch something that large.
