The first place I would check in correcting transmission errors is the fluid. Make sure you check it with the vehicle at operating temperature, while the engine is running and parked on level ground.

If the fluid is low add the appropriate amount of fluid to bring it to full. If it is burned you may have some internal issue and should consider seeking the assistance of one knowledgeable in transmission work.

Another place to look is at the fuse panel in the engine compartment. Check the fuses, either visually or with a fuse tester (the more efficient and effective way). You may think also about checking the relays. The easiest way to do this is to switch the relay for the transmission with the relay for the horn and then try to blow your horn. If the horn does not sound then you know it's the relay and that it should be replaced.

I have also had some success clearing some transmission troubles on these cars by pulling and cleaning each fuse for the transmission. I usually use a can of electrical parts cleaner (available at most auto parts stores), a good unused eraser (I like the white ones that you can click into place and then retract), and some dielectric grease (also available at auto parts stores). If you would like to do a super efficient job you can pull the fuse box and clean the contacts from the underside as well. Just be sure to disconnect the battery (negative first) and follow safe working procedures.

While you're in there you may consider replacing the engine coolant temp sensor as there have been many reported problems with the ones originally placed in the vehicle and can cause a whole host of problems with these cars.

2003 toyota echo when shifting above 45 mph makes a loud high rpm noise especially on the highway


If it is not going into overdrive or lockup it could be the fluid or an electrical problem. Some of the shifting is controlled by solenoids now.
You may have to get a transmission shop to evaluate it for you.

1995 oldsmobile- car makes a surging or jerking at 45 mph


That is the speed when it would normally shift into overdrive or the torque converter would go into lockup.
It is also when the engine would be working hard and a slight miss could be magnified.
You may want to have a transmission shop test drive it for their opinion.

DEFINITE LURCH IN 1ST AND 2ND GEAR,


This may apply. ...............................

Carry out the adaptation drive cycle road test:

Note: This process must be carried out in normal mode (not sports mode). On a flat road, the transmission fluid temperature must be above 60° C (140° f) and below 100° C (212° f) (vehicle at normal operating temperature will ensure that the transmission fluid temperature is above 60° C (140° f)).
9. Accelerate from rest with light throttle (do not exceed the upper rev limit in appendix 1). 1-2, 2-3, 3-4 shifts must occur with engine speed between the following limits:.
Note: Do not move the accelerator pedal during shifts.

• 3.0L VIN ALL 1800 - 2000 rpm
• 4.2L N/A Prior VIN M96321 1450 - 1600 rpm
• 4.2L N/A From VIN M963221550 - 1700 rpm

10. Continue to accelerate gently to 50 mph (80 km/h) so that transmission shifts into 5th gear.
11. Go into overrun and let the transmission shift down into 4th gear without braking.
12. Brake gently to a standstill and hold footbrake on for at least 15 seconds.
13. This process should be carried out at least five times.

Transmission slipping or stalling around 45 mph and down shifts


if fluid isn't burned, shifts aren't slipping or flairing and you did not find a large amount of debris in the pan, chances are that the electronic shift control is malfunctioning. Have someone check it out.

Ect power?


The ECT button stand for Electronically Controlled Transmission. In short, what the button does is change the upshift points for the auto trans. Normally, the 1-2 upshift is at 15-19 mph, pressing the button changes the shift mph form 15-19 to 19-22/23. More often than not, this feature wiooould be used if you are hauling a heay load, and the ECT gets you up to speed faster, via the longer time as mentioned above re the shift mphs. Not very useful with normal driving, it really does not do much without a heavy load.

2005 Toyota Corolla with 36,000 miles Transmission now "jumps" into gears


hi,
when the check engine light comes on, your car goes into a mode where instead of everything being normal, things are forced, to try and compensate for something else being wrong. It most likely does need a new timing belt, and a complete tuneup INCLUDING plugs and wires. we have a 1984 toyota corolla and it purrs like ground rice, I suggest the tuneup to continue proper rice production.
