Question about 1995 Ford Aerostar

1 Answer

Aerostar transmission 95 aerostar not awd, transmission will not engage in od but will regular drive. when you go to overdrive you fill a slight tug and it imediatley releases and you have to go to reverse, let it engage then go to regular drive and stay there. when you get up to 40 to 45 you can shift to od and it will pull fine untill it trys to downshift then it will lose grip and you have to stop go to reverse and go to regular drive . trans does not do that if you stay in regular drive. trans has not wanted to shift from first to second for about 10,000 miles without lifting on gas in od or regular drive, its not low on fluid. could it be sensor or something?

    I have the exact same problem with a 94 model. Sometimes it will not engage in reverse or drive. Sometimes I can wait about 5 seconds and it will engage. Other times I have to shut it off and restart then quickly shift from park into reverse or drive.

The aerostar tranny cooler sits too low away from the trans and tends to become blocked and restrict the flow to the tranny It could not hurt to remove it and flush the cooler out I have had a few aerostars and I have had to flush them all,the tranny fluid came out very dark and smelled very burnt it may not solve your issue but maybe. It has solved a shifting issue for me the 1-2 is smooth as silk now.

In a 95 chevy blazer 4 by 4 Should the transmission be in drive or overdrive for normal driving condition?


normal drive yes the od unit comes on after 40 mph is reached and maintained above that speed , if you happen to engage 4x4 then the od shouldn't come on at any speed , point of reminder this model and year has a recurrent problem with 4x4 transfer case not disengaging all the way , and causes some delay in transfer of engine power to proper drive axles , its mostly caused by improper transfer case lube oil changes and dirt builds up inside it causing all sort of mayhem

Should I keep overdrive on or off? also should keep ECT on or off?


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.

I hope my assistance answers your question.

Thanks for choosing FixYa today!

Transmission will not shift into overdrive on a 2003 4.7L Jeep


This will not repair the problem but it will cause your OD to shift. Caution: you need a long stretch of highway and sparse traffic.
After trying everything I could think of, I noticed that when the automatic locks failed to engage (at around 15mph) that's when the transmission would not shift into OD. So, now when the locks don't lock and the transmission doesn't shift to OD, I put the transmission in neutral and turn off the ignition and let it coast to a slow speed (see above caution). When I start the engine again and put the transmission back into drive, the locks engage and so does the OD. Works for me. I'm currently doing research on what causes the locks to engage automatically. I'm thinking it will be a vacum or a switch. BTW, mannually engaging the locks will not work. Good luck. Hope it works for you.

What is the proper way of using overdrive,how and when you have to use it?


If you are not climbing steep hills or towing, leave it on all the time. Turn it off for low speed/high strain driving like towing, climbing and off-roading.

i hope this helps

Transmission problem on 95 cutlass ciera


Overdrive has two important factors involving when and if it turns on besides being in the proper gear shift position. One is tthe car has to FIRST reach operating temps before it will engage the TCC ( torque converter clutch ). That could involve a faulty thermostat, or short distance drives, Second important factor WILL DISENGAGE WHEN STEPPING ON THE BRAKE PEDAL. A brake switch could be misadjusted , and without you stepping on the brake, the computer thinks you are and wont engage TCC. Hope this helps.

What are these buttons for? e t c drive & side of shifter


The ETC switch is a transmission control device. When it is not active, the transmissions shifts normally. When the ETC is engaged, it alters the shift points.
Example: the 1-2 upshift occurs normally between 18-20 mph. Now, say you are towing something, or are carrying a heavy load...engage the ETC, and the trans computer will "hold" the 1-2 upshift until 22-24 mph. It is just for that, prolonging the shift points, due to load.

The switch on the side of the shifter is for the Overdrive. Engaged (the OD light is off) the transmission shifts into overdrive. This saves you gas. When the button is dis-engaged (the OD OFF light is on) , the transmission does NOT shift into overdrive. It is best to leave the overdrive ON, and the ECT OFF to obtain maximum fuel mileage. I hope this has answered your question. Please feel free to comment back if you have any other questions. Thanks for chosing FixYa for assistance.

Overdrive indication light


first of all, does it shift into overdrive, I would check and see first of all if you drive it and it does go to O.D. then press the button once, does it not go to O.D. you can do this while driving, when running about 45 press the button once, do you feel it downshift. if yes then your light is burnt out...if no run an OBDII check to see if there are nay codes for the transmission. if that checks out theN i would go for the switch being bad..
