Had problem with 86 Lincoln not shifting properly when cold. I assumed it was because the fluid was thicker and would be more affected by a clogged filter. I had the transmiss…ion flushed and the filter cleaned and it worked perfectly from then on.
Answer . \nHave your transmission flushed.($120-140) My 87 Accord did the same thing. Unfortunately, it needed a rebuild a year later. Good luck.. Answer . \nIs level l…ow?
How do you stop a 1997 manual transmission Plymouth Breeze from idling high in neutral until you come to a complete stop and then idles down?
Spray down the throttle body outside to clean it & prevent anything from sticking there. Then while the engine is running spray inside intake as long as possible without stall…ing the engine. This should do it.
My 2002 Dodge Neon has rough idle 500 RPM after stopping at red light when I turn the steering wheel or shift to neutral the RPM goes back to normal any suggestions?
Same problem here Hey, my 2002 Neon just started doing that EXACT same thing. The initial diagnosis from the dealership is that it's a transmission problem. Doesn't really ma…ke sense to me, but they're going to tear into it a week from tomorrow (May 15, 2006) so I'll let you know what they find. Twila Hi there I had the same problem with my car a few years ago. After some arm twisting at the dealership I got them to preform the PCM - Low Vehicle Performance TSB 18-013-02 created 04/22/02 This should be all that it needs. It has some thing to do with the way the pcm reads the rpm. It takes about 20 mins for the dealer to flash and install the updated software for your car. Richard Make sure that you only have the computer flashed by the dealer. Many independent shops have bad ROMs. I had my 2004 Neon flashed during a routine visit to the shop that I've been taking my older cars ('77 Mustang, '86 Camaro, '68 Corvair) to for years. Rough idle problem showed up the next day. Had the dealer flash it and everything went back to normal. I asked my indi shop what the deal was and he said that Dodge often doesn't release the proper ROMs outside of the family. Same goes for computerized alignment specs and such. Cilynx Had same problem with rough idle and check engine light codes for random cylinder misfire. After replacing plugs, wires and coil pack, turns out the only problem was that the spark plugs were not gapped properly! Re-gapped plugs and runs better than ever now! Easy fix for me. Try checking this before wasting alot of $$$!!!
What is wrong with a 1997 SC2 that starts and idles OK until the transmission is in gear and the car is moving then the engine speeds up until the car stops moving and the transmission is in neutral?
Answer . If the transmission is in neutral and the engine is racing would indicate that your throttle body cable is binding somewhere. Check the assembly, check by the gas …pedal.. Answer . \nI have checked with a dealer on the same problem. I have a 96 sc2 and it does the same thing. They told me it idles down due to the engine computer. They said if it is cold outside it will idle high like this. Once it started getting warm outside mine stopped doing this. Please let me know if you have found out anything.\n. \email@example.com. Answer . Mine was doing the same thing. I changed the temp sensor and it worked. yours is probably cracked.
Why does the engine make a noise the transmission doesn't shift and temperature go up when accelerating?
ANSWER . Don't keep driving it like that you will damage your engine by going over the proper rpm. I know something that could cause that to happen you must check your trans…mission fluids, if that's fine check the oil pumps because that's what clutches your gears. This happened with my Dad's van. It wouldn't change gears so I checked those things. They were fine but there are sensors that connect to the transmission that were bad and I got a new one and replaced it. That ended up fixing the problem. That may solve your problem.. ANSWER. The transmission may need replacing. If you hear a loud whining noise when you suspect that the transmission should shift, the servos are probably going bad. You should definitely check your fluids. Make sure you have your oil changed every 3000 or so miles and have your transmission flushed every 30,000 miles. When you are doing your self diagnostic by checking your transmission fluid, it should be pink and translucent. If your transmission oil looks like motor oil it is long overdue for a flush. If your transmission is not shifting properly and your engine temperature is going up, it needs to be seen by a mechanic. You also shouldn't drive it, if the transmission is damaged driving it further will make it worse. An important caveat, if your transmission fluid looks white and frothy, almost like soap, then your cooling system is probably leaking into your transmission system. If that is the case then your transmission will almost definitely need a rebuild.
What is causing a 1986 4x4 Diesel Suburban to lose power as if in neutral until brought to a stop and driven in 4WLow for a while then shifted back to 2W or 4WHigh?
well im not an expert but it sounds like the hydralic brake booster is sucking power from from the motor possibly due to a malfunction in the booster or a clog in a line i bel…ieve the booster requires 12-15hp to operate, an alternator 10hp and all your accserories add up if one requires more your motor will lag down, as for having to be in 4low im guessing because the engine in 4low it has enough low gearing that it doesnt require much hp to move it so the "excess"/unused hp is being put to the booster where it bluids pressure till u use it enough to drain it again, that's what i think but im just a self trained mechanic in college so i may be wrong but it may help start u off
Your 1996 Dodge Ram 1500 5.2 L Automatic Transmission is not shifting properly in order to get it to shift from 3 to 4 you have to shift it into neutral for a second and then back to Drive.?
This is a very common problem on Dodge transmissions and I'm about to fix this problem myself on my 1997 5.9L 1500. It's most likely being caused by faulty ATF selenoids. Repl…acing these selenoids will fix your problems, but most likely only temporarely. They usually become clogged due to metal shavings getting caught in the screen filter of the selenoid. I'm not positive where the metal shavings come from, but I would say the torque convertor. For a long-term fix I would recommend replacing the transmission with a lower mileage tranny..

Does shifting to neutral at stoplights affect the long term health of automatic transmission engines?
It shortens the life of your transmission by shifting in and out of gear to get the longest life you would leave it in drive at all times every time you shift in and out of ge…ar you are putting pressure on the plates when going back in gear causing wear and tear also make shure you are completely stopped when going from forward to reverse for the best tranny life I disagree. Long periods of idling while in gear & holding the brake, such as stop lights, trains etc. generates a LOT of excess heat, which is a Trannys worst enemy. Shifting into Neutral then back into gear is not all that hard on Trannys. I don't believe the Engine is affected in either case.
Not required. In an auto transmission the gear is at its lowest when the brake is engaged and uses the same amount of fuel as in neutral. In manual transmission, I have seen f…ew people shifting to neutral but again it is not required, you may put it at the lowest gear and keep your brake and clutch engaged while at stop light.
1990 Volvo 240DL auto transmission won't shift up from second until very high revs and slips out without positive and increased engine speed Works fine from a standing stop but want to stay 1st or 2nd?
Flush the trans,replace filter perhaps, valve body needs reworking.
Is shifting to neutral with an automatic transmission and coasting down hills detrimental to the car's engine and transmission?
This is not something I would recommend you do. It may do no harm and yet it may very well cause a build up of pressure and transmission problems. It will not hurt the engine …at all, but I would not do this for fear of hurting the transmission. I am not sure if it will hurt or not, so until you know for sure, do not do it. My guess is that this may do harm. A new transmission can be very expensive.

2003 Hyundai Accent 4 door The check engine light comes on and then when I stop the transmission doesn't want to go I have to manually shift my trannie its an automatic Please help?
Try first with Trans-X, transmission additive before go to shop major repairs
In Transmissions and Drivetrains
Any unnecessary shifts cause additional wear on the shift mechanism, but that's a minor consideration. At a long signal light or train crossing, it's better for the transmissi…on to shift into neutral than to keep it in drive with foot on the brake, or if a manual, better in neutral than holding in the clutch all that time.

it shouldnt, check or change all of the spark plugs, change the oil, and reset the idle
