yeah listen to that question overdrive that kicks in around 50 to 55
It kicks off electronic overdrive
the overdrive is used to save gas. it is an additional gear after your final gear in the transmission. this gear usually kicks in at higher speeds (maybe 50+). you will notice the tach drop down about 500 rpm's as the vehicle kicks into overdrive. it does not make your car go faster or slower. you will not have be able to accelerate as fast in overdrive as you will in other gears. if it is an automatic overdrive then as you slow down the overdrive will automatically be taken off.
No overdrive but the non turbo 4cyl had a lock out torque converter that usually kicks in at about 46-48 mph. Gave an extra 2+mpg. Not available on turbo cars.
It's usually on all the time unless you press the button each time you start the car. I think that normally the overdrive kicks in around 45 MPH.
sounds like overdrive clucth pack is burned up. you can just replace the trans to fix it or a cheaper way to go is to replace just the overdrive clutch pack
sounds like mine. it was the transmission. sorry. it got up to about 1500 rpm's and then bucked and dropped. would not go past 1500 rpm's at all.
If it has a 4L60E then you need a new transmission control solenoid inside the transmission. If you have the 4L80E then you need to find and change the transmission control module
probley has a speedo problem. ot's a spring on the side of the trany that kicks in the over drive
If the engine sounds loud like it's going faster than you really are it could be that you have lost your overdrive gear in the transmission. Once you hit freeway speeds, the automatic overdrive kicks in. If the engine seems to be operating normal, your tachometer might be faulty. Ken
