My 92 cadillac deville shift at 30 miles per hour and again at 60 do you think its my transmission speed sensor


its very possible ,that's where tranny gets info to shift all your main gear shifting should be done by 35 mph and after 55 is overdrive the other is if you take it for a drive and manualy shift it out from lowest gear to highest and see how it functions, so you can feel the shifting advance then try it again just in drive only and see if you can feel the gears shift out , have you serviced tranny ? is it a high millage car it is 23 years old ,

1994 shift only when overdrive is off.


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)

I have a 95 lexus es300. a o/d off light is on my dash and won't go off


That is called the OVERDRIVE OFF and yes it will affect you transmission. The overdrive is your highest gear, used for highway cruising and will promote the best fuel economy. You have an Overdrive switch in the vehicle. It is either on the shifter knob or on the center console/dash. It allows you to disable the overdrive if you desire. It sounds like you turned it off unwittingly.

No reverse gear, only low gear no upper gears or overdrive could this be a modulator valve


I do not think 99 has a vacuum modulator but even if it does that will not keep it from going in to reverse. No it has a selonoid pack that may the problem. You need to get it diagnosed by an honest transmission shop. Hope this helps leave a comment.

Transmission doesnt shift into overdrive


Does the cruise work? is the check engine light off when driving? Does the overdrive off light come on and go out as you push the button on the gearshift? Does the speedometer work normally? Any of these things can make it not go into high gear. Does the gearshft work smoothly and seem to be in the correct gear? Are the motormounts good enought that the engine doesn't rock around too much and pull on the cable? Their's a few electrical connectors connected to the transmission, are they connected and not leaking oil and worn or damaged. Most of the time this problem can be solved by carefully looking over these things and you'll find some asquew. If not and the check engine light or overdrive off light is'nt on the there's transmission troble and you need to show up for your free roadtest at a transmission shop and listen to what they have to say. If it sounds reasonable and straight forward do it it it sounds like thier guessing take it somewhere else. Your Cadillac dealer will be right but they may build up a strong bill before they fix the car. and want still more to do the repairs.

HAVE A 2001 CADILLAC.WILL NOT GO INTO OVERDRIVE. HAVE FLIUD DRAINED AND NEW SCREEN INSTALLED.


Welcome to FixYa.com Though we here at FixYa can help lead you to the right direction and most of the time walk you through the repair, but transmission problems are the hardest. I can tell you what has happen to these cars when overdrive goes out. It would be easier to have the transmission checked out by a professional to ensure the best quality repair. How many miles on car ? Have you regularly changed the filter and fluid at the specified times ruffly 45,000.00 miles ? Does reverse bang hard into gear ? Regards, Lee Davidian

Where is the speed sensor located on a 2000 jeep Grand cherokee v6 4.0 L?


Since you have the die hard, can not kill 4.0, I believe this mated with the 42RE transmission. My understanding It use's a single sensor (located on the overdrive gear case, over the park gear).The 42RE transmissions use a single sensor (located on the overdrive gear case, over the park gear). The 42RE transmissions use a single sensor (located on the overdrive gear case, over the park gear).
