Works fine until the tranny reaches full temp then will unlock when cruizing speed is reached. Will lock when accelerating slightly but will unlock again when traveling on flat highway when maintaining speed.

SOURCE: 318ti M44 acceleration problem

Have someone handy to press the gas pedal for you after the engine has warmed up well; best if driven.

While you listen at the exhaust pipe, have your helper increase the revs slowly and note whether the exhaust note changes to a hiss, instead of the sound of an engine firing.

You may have a decayed catalytic convertor and when they come apart inside, they can clog mufflers and resonators (the second, smaller muffler).

I've had this happen on more than one car and when it happened on a Fiat Strada years ago, since the routing of the system was fairly straight and made of heavier gauge stainless steel, I fired two shots with a .357 magnum into the tailpipe.
Never had another problem with it.

I would say either  transmission control module or the torque converter.

SOURCE: My key will open my trunk, but not unlock my doors or start my car.

Open the trunk. Take out the trunk lid light - take the bulb out of the fixture. Place a 12 volt battery in the trunk. Take an alligator clip jumper wire - connect one end to the negative terminal of the battery and the other end of the jumper wire to the car chassis - make sure it is a good connection and is not on a painted surface - I place mine on a bolt on the rear light panel. Take another alligator clip jumper wire and connect one end to the 12 volt positive terminal and connect the other end to the short end of the light connectors (there are two connectors for the light - one is short and one is long). This should give you enough voltage to unlock the doors. I had to figure this out and have used it twice on my BMW.

I have a 1994 Nissan Pathfinder and the tranny won't go into Park so what is the problem and how do I fix it


Will the selector lever in the cab click into Park, or does the selector lever not reach that position any longer?
If it physically cannot reach the position and lock into it as per usual, then the linkage underneath needs adjustment.
if it reaches and clicks into Park position but the transmission does not lock, then there is a problem with the pawl not tngaging and locking the trans.
Always try to adjust the linkage before delving into the trans in cars something is worn, broken or has slipped put of position.

Camry rear seat won't unlock


The plastic pull on the top of the seat may have been screwed down too much. If that happens, it will not allowing the lock mechanism to fully unlock. Unscrew the top plastic pull a little at a time and at the same time reach around and pull the lock leaver up until it is in the full unlock position. You should then be able to pull the plastic lever up normally and fold down the seat.

My 97 ford taurus transmission shifts fine but it will not go in to the over drive and the o,d light blinks off and on what do I do?


The OD light flashing is usually a sign the TC is overheating. I know it will come on when the ATX fluid hits 300F.

Coasting in neutral will cook a TC if done for very long. This is because the TC is spinning at a relatively higher engine speed but the tranny pump is not putting out enough fluid to keep it cool.

A locked TC is always better for the tranny and full power output. An unlocked TC is wasting energy churning up the fluid and causing a parasitic drag.

Once tranny fluid has reached this temp it is junk and should be changed. If you don't then it gets worse and worse and soon the tranny will fail.

Start with changing the filter and fluid and check for shifting issues after that. If it is shifting to O/D and clean, you have fixed the problem. If not, it could be a solenoid problem, a torque converter problem or worse. That is when your real work begins. Let's just hope the problem is the fluid is not flowing properly and the filter and fluid replacement fixes the problem.

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

My 1996 GMC Suburban has 170600 miles on it. In the last week, it drives fine until you travel about 1/4 mile & reach 30 mph. Then, you loose acceleration. When you push the gas, the engine just revs....


Try dropping the tranny fluid and changing the tranny filter and filling with fresh fluid. Sounds like the tranny is sleeping between shifts.

How do i replace a tcc solenid in a 95 beretta 3.1 v-6


its just a sensor plug on the tranny, the solenoid reads the speed of the transmission (car) and sends the signal to the computer which identifies that the car has reached proper crusing speed and is not under heavey load (full throttle) it then "locK" the torque converter to not allow any slippage like a standard automatic torque converter, basically making the torque converter act like a clutch,,, thus the name TCC torque converter clutch. So to help you out just unlug the sensor/solenoid and it will stop locking up your converter. Problem solved! MOney saved 2 to 3 hundred bucks!

1994 toyota paseo: overdrive problem


I would start with replacing your tranny fluid. black is no good. your tranny should hold about 7 qts of fluid. The tranny fluid runs through your radiator to help keep it cool. If your thermostat is stuck closed your eng coolant won't circulate and the coolant will get hotter inside your radiator. thus making your tranny fluid hotter and breaking it down. After time it will turn black from getting too hot. Let your car warm up to normal operating temperture then grab your upper radiator hose. It should be very warm. If not your thermostat is stuck closed.

94 sunbird stalls when stopping


Could be an idle air control problem, or possible vacuum booster trouble, have also seen the baffle broken in the GM tanks and when you brake hard the engine dies. Fill the tank and try it, if it doesn't do it the baffle is bad.
