Car shifts through all four gears fine, but will not kick into overdrive when going over 50/60 mph. In order to accelerate faster, the engine RPMs compensate (by going upwards of 2500/3000 rpm), whereas in the past, overdrive would kick in and take the stress off the engine (in the past to go 65 to 70 would be around 1800 to 2000 rpm). The issue started the day the temperature dropped below 0, and the issue has not gone away with warmer weather. I took the car to have a transmission shop evaluate. They think the car is working as it should, no codes/errors, but I know the overdrive is not working as it should. The transmission fluid has been changed, filter cleaned, and coolent replaced. Still not going into overdrive at high speeds. What is the next thing to check? Thank you for your assistance.
This happened to my 2001 Regal... There is a factory recall on the Catalytic Converter going bad. I had mine replaced with the recall and haven't had a problem since
Do yourself a favor & get it scanned at transmission shop, or dealer & fixed as needed,(within reason) . Delaying it could cost lots of money. A rebuilt is about $1500-$2000.
If you're only in "D", you should switch to "OD" when driving at higher speeds. "D" only allows you to move up to third gear whereas "OD" will move you into fourth. You're over-working your transmission by driving in "D".
Try changing the transmission fluid and transmission fluid filter. It is a fairly easy but kind of messy job. Just buy the new fluid and filter, Grab your metric socket set and go at it. NEVER WORK UNDERNEATH A HOT VEHICLE. You have to pull the transmission pan to do this job. When you break the gasket seal several quarts (liters) of transmission fluid will cascade down on you. Be ready for it. Don't forget that when it stops draining there is still a lot of fluid left in the pan. When you finish cleaning up the fluid clean the gunk out of the pan. Install the new filter and reinstall the pan with a new gasket. Do not over torque the pan or filter bolts. If you strip them out or break them off you will need professional help to repair it. Refill the transmission with fluid. It should take six or seven liters.
I don't think any body can help you here.
any mechanic have to drive the car to experiece the problem . Impossible to fix it over the phone.
Take it to mechanic shop to prevent futher damage.

Does the car have a button on the shifter handle somewhere to disable overdrive? Also, there is a plug on the transmission that must be plugged in to engage overdrive so check to make sure it is plugged in correctly.
I have a 92 Crown Vic first and second works fine reverse works fine when it shifts in the third gear it goes to slipping and overdraft can you help me fix this problem thank you
first thing to check is transmission oil level and quality. If that is fine than your looking at either a valve body problem (valve body is what controls the selection of gears) or possibly a problem with the bands on the planetary gear set, they can be tightened in certain models. However i dont think it is the bands. Does the overdrive only engage 4th gear? or does it feel like the gear ratios are different between overdrive and normal before the problem happened? some overdrive buttons engage final gear and some do as much as change gear ratios like in a cvt (contantly variable transmission) and some just change the timing in the gear changes to provide more rpm/power. My best guess is that the valve controlling the overdrive in the valve body has failed and therefor you dont get a response from the transmission (i.e no gear shifting when overdrive is selected)
Hello. Welcome to FixYa. I am Toyota Ed, and I will be assisting you today.
The Overdrive function allows the transmission to shift an extra time, sort of like selecting 5th gear in a 5 speed manual transmission. The Overdrive, when used, will save you gas, as the engine is no longer maintaining a high RPM at normal driving speed. Look at the tach whilst driving about 45 mph, and engage/disengage the OD. You will see the tach RPM raise when the OD is off.
More RPM = lower fuel mileage,
The ECT is a different circumstance. The ECT button is used primarily when you have a heavy load in the car, or are towing something. All the ECT button does, when it is engaged, is lengthen the shift points as the transmission upshifts. Normally, the transaxle will shift into 2nd gear at 18-21 mph. When the ECT is engaged, the transaxle will shift in the area of 22 -24 mph. In short, the ECT just makes the time to the 1-2 and the 2-3 upshift longer, to compensate for the additional load being carried/towed.

When the car is just cruising along at approx.50+ MPH push the O/D button. You should feel the gears change higher and if you have an RPM guage then it should drop as well to fewer RPMs. This would be normal driving conditions. O/D will not kick in until the last regular gear (3rd or 4th depending on model) had been shifted into. O/D automatically kicks out when slowing down and the transmission shifts to a lower gear. Thus the O/D has no function at slower speeds/gears and does not need to be shifted ( on or off ) except in the very first example given here.
This is what my 04 Kia Rio is doing exactly. I was told that the TCM and Shift Solenoid "C" is faulty. Am trying to figure out how to go about fixing that without paying more than the car is worth. My tech checked with the local Kia dealership and the TCM new is I think around $700. You also have to buy the program to tell this high dollar part what to do and that is right at $100. I have found that sometimes if I let the car warm up and then keep hitting the overdrive button, eventually it starts shifting correctly.
Hi. 2005 Corolla CE. It's normal. They tend to do this when upshifting form 1st to 2nd gear. No timing chain readjustment needed.
96 Corolla. Overdrive not working properly, if not engaging after 45mph constantly. If driving on the city, is normal, but not after 45mph, when the car is trying to engage overdrive in order to save gas and preserve the trans gears. If not able to get help at the dealership, find another one and explain them the situation.
