98 Toyota Corolla weirdness by irismg
Jul 14, 2007 (10:37 am)

For a couple of weeks, not only has the rain been turning streets into rivers, but my transmission has started doing weird things. I've noticed that when the car is slowing down, say, to pull into a parking spot, it of course has to downshift, but then it seems to forget it's in gear, like it's in neutral, and pedaling does nothing but rev the engine, and then it remembers it's in gear and then I can pull in.
 
I don't have any trouble from a standing start or from a dead stop, I have no problems (yet) accelerating. And most frustrating, it doesn't do it all the time. Every now and then from a stop light it will take longer to shift into second. But again, it's not everyday.
 
Last weekend we got a break from the rain, and it seemed OK. This week the rains came again, and the problems started again.
 
This morning as I was getting an oil change, my service attendant said my trans fluid was low and topped it up. He said it looked as if it had been leaking at some point. However, I've never noticed any puddles.
 
My question is, could any of this weirdness be weather-related? And, since the fluid has now been topped up, should I see an improvement in its behavior? My service man told me to take it to a transmission specialist soon to have it checked out, but I don't trust people who are in the business of selling you a transmission! In the meantime, I'd like to get a feel for what could be the problem.
 
Thanks in advance!

How low was it? Low fluid level can cause the symptoms your describing. On a 9 year old car it's very likely you could have a small leak.

Sorry, my service man didn't tell me how much, he just said he "topped it up".
 
Do you think it's possible for it to leak and not see anything on the ground or floor? I'm going to take it out tonight to see if it's acting better.
 
Thanks for answering me. It's frustrating, even if I do have myself to blame by not paying closer attention.

I have a 1999 93 turbo, and it recently did that same squeal, which comes only from the right rear wheel. Any suggestions on the diagnosis or repair? Did you have any work done to repair it?

When a car gets that age you should check under the hood frequently - time can cause problems just as much as mileage.

I have 2001 Civic LX.
The Car just stopped on freeway, The mechanic told me that the transmission is gone. The dealer wants $3500 for a remanufactured transmission.
 
What do not understand is how come the Auto transmission gave up with 72,000 Miles.
I know that 2000 Civic had some transmission problems. Does anyone know or heard about 2001 civic transmission problem?

'98 Lexus ES300 rough shift problem by sean300

Hi. I own a 1998 Lexus ES300 with 150,000 miles. When shifting out of park to reverse (backing up), I get a rough shift. I can feel a jerk which is accompanied by a short but loud thump. This happens when I leave for work in the morning or when leaving the office for the evening and it just began this week. I keep up on the maintenance including the tranny. Has anyone experienced this and how do I rectify it?

GM 4T60E Trans Problem - Grand Am(no 4th gear) by ron528
Aug 28, 2007 (12:25 pm)

I have had a 98 Pontiac Grand Am for about 2 weeks now. It has the 2.4 liter 4 cyl so its suppose to have the 4T60E transmission. Well it won't go into 4th gear at highway speeds. First day I owned it the engine wiring melted and the dealer replaced the engine wiring harness.
  
First, secnod, and third gears wortk fine. Fluid looks and smells good. What could cause this transmission not to go into 4th gear? It tachs 3,000 rpm at 60 mph in third gear, when I put it into drive, still at 3,000 rpm at 60 mph.
  
Any help will be greatly appreciated!

Since you didn't mention uneven shifting I would look for the simple. If the thermostat isn't making the motor heat up enough the transmission doesn't go into 4th gear. What does the temperature gauge say?
 
If the car is going 40 in 3rd at light throttle the transmission should have the torque converter clutch lockup. Does it? You can test that by slightly accelerating and touching the brake pedal to make it think you're braking and the transmission should unlock the TCC and the motor speed will increase. It will speed up if you just push down a noticeable amount on the pedal with the 4T60 if I recall correctly. What happens there? Is the TCC locking up?
 
It might be a sensor for temperature on the motor not telling the computer that the car is warm even if the thermostat is heating it up. The computer may use a different sensor from the one for the instrument panel.
