So I was driving home today and my car started making a high pitch squealing noise (my car started sounding like a toyota prius) I went to give it some gas and the engine light turned on and the rpm's went up fairly quickly but my car wouldn't really accelerate. I slowly drove it home and the whole way home the sound continued and I had to drive slowly. Finally a couple blocks from my home I hit a stop sign and as I tried to accelerate my car wouldn't go anywhere. The rpm's went up but I wasn't moving. I pushed it into a parking lot (It would not move in park but I could push it in neutral) and turned the engine off. under the hood everything looks fine but I noticed on the engine there looked like a screw was missing. The car starts and everything just wont move which made me think it was a transmission problem, (but I was able to switch from park to neutral and everything) but I have never had any problems or indications of this before. Is it possible for my car to have these symptoms just from missing a screw on the engine? Or am I looking at a much more expensive repair? Any help is greatly appreciated and I'm sorry I'm not more mechanic savvy. Thanks again,
You are going to have to give us more than "I noticed on the engine there looked like a screw was missing". There aren't any screws on our cars that are NOT needed for something, or they wouldn't have been there to begin with.
How about a picture of where you think the screw is missing? You'll probably have to post 5 or so comments before the forum will allow you to post pictures, so get started!
To check for trouble codes-put key in ignition, turn key-on-off-on-off-on, and look in the EVIC (computer sreen on dash, next to speedometer) and write down any numbers that come up, report back here and we'll tey to help...
Alright I checked the trouble codes and nothing came up just read ------- and then dOne. I was able to start it and drive it home at about 3 mph. I will take some pictures of those screws I was talking about when I get some more time. Thanks for the help so far. Wish I could check my trans fluid, but there's no dip stick. Anyways I'll check in again later. thanks
A little update:
The codes read PO700 and PO730
PO700:Transmission Control System
PO730:Gear Ratio incorrect.
Leading to a transmission problem.
The odd thing is the car will run and drive fine 2 times out of 3 (almost like the PO730 only comes up sometimes, I've heard when the code is sent to the system you won't be able to get out of neutral). I really don't think this is a mechanical error but electrical.
Anyways the shop I took it to told me the "Whole transmission" has to be replaced, but once I told them that I don't have the money and I was going to tow it home and just sell the car they changed their opinions they said "well leave it with us for a day or two more and we will check a few more things and you won't have to pay a penny over the cost for the diagnostic" I said fine but was skeptical because the change in pace seemed very sketchy. When I came back the word solenoids was being thrown around quite a bit.
I just remembered, while replacing my thermostat a couple months ago I had another code come up for a speed sensor. The guy at the shop told me it's the ABS speed sensor and I could wait a couple months to replace it because it wasn't detrimental to the system. Do you think there is any correlation between these two problems? I saw that a common fix to these kind of problems is replacing a speed sensor but I know there are many speed sensors on these cars.
