sounds like the (VSS)vehicle speed sensor is bad causing the speedo not to work and the transmission is not shifting properly because the computer can not tell how fast the car is going,have your local mechanic fix it asap so toy do not do any engine or transmission far as the heater stopping,I dont thing they are related.I will get back to you on the blower have a good day DB

    sounds like you have a faulty VSS (vehicle speed sensor)its a very important input sensor for the computer,it lets the comp. know vehicle speed so it can shift the gears properly,so whats possibly happening is the vehicle is not shifting properly,the heater problem is a seperate problem,so have your mechanic scan the comp. to confirm and more than likely thats the issue. have a good day DB

I have a 1996 Honda Accord with 268k miles that sputters at the same timethe speedometer needle fluctuates wildly. But I do have a new Vehicle Speed Sensor. This typically only happens when the engin

I am no Honda expert, but a similar problem happened to my ex sister in-laws Ford Taurus. The speed odometer would jump around and it had trouble shifting (automatic transmission). After driving it I changed out the speed odometer sensor on the transmission and it's been fine ever since. I changed out the sensor because if the cars computer cannot tell how fast the car is traveling then fail safes in place go into effect and the computer will do it's best to keep the cars rpm's down based on the speed indicator and not let it shift or shift properly either. If it's getting false speeds then it will shut down the motor when the speed gets to high and allow it to run as the speeds fall (jumping speed odometer needle). It effects the transmission shift points also. It will either shift erratically or not shift out of say 2nd gear, so that the cars engine can't get damaged based on what signal the speed sensor is sending the computer.

My 98 z71 won't shift when the indicter light goes

Your car reads off of the trans. Sensors to shift. You are going to need an input and output sensor, that will fix your speedometer also.

99 chrysler LHS odometer not working & engine light on

Having the vehicle checked for DTC'S - diagnostic trouble code's could point you in a diagnostic direction . Most auto part stores will check them for free .Not shifting ,odometer not work would make me believe the VSS - vehicle speed sensor is bad , engine light coming on has to do with the engine management system , not the engine mechanical ! You don't know about OBD 2 - onboard diagnostic's . The check engine light it's called ,comes on when the vehicle is polluting 1 & 1/2 times more then the EPA allows . Your best bet mite be to take it to a qualified repair shop that knows how it works .

The sped ometer and odometer has quit,now i notice sometimes the transmission does not shift from first without stopping placing it in park. Turn off switch and start over and it will down shift at times

depending on the model and year there are so many sensors and solenoids on the trans and engine that it is going to be hard to fix without a scan tool.......but if this started at the same time the odometer and the speedo quit working i would be looking at the speed sensor in the trans and then the speed sensor that is made in the speedo head that both can make the speedo head and the odometer not work......i hope that this info will help you and if ican be of any other help let me know.......let me and fixya know if this was any help to you and a thumbs up would be appreciated.....good luck and have a blessed day............

F-350 speed/odometer not working and shifting hard

there is a speed sensor on the top of the rear differential. either the sensor is bad or it has become unplugged. when the truck doesnt know how fast it is going, the trans goes into "limp mode" to protect itself...whic causes it to shift hard and if u look you'll notice the o/d light is blinking
