I was on highway doing 75 with cruise on. All of sudden the truck downshifts and continued to do this while on highway but not surface streets. Is it tran auto relay switch or solenoid (I have no leaking). 1996 s10 4.3l v6...
View 2 RepliesI have a '96 Chevy Silverado that twice (in about as many months) has had some trouble starting. When I turn the key the engine starts to crank, then there is a loud pop and the engine stops. When I crank it again the engine will start, although more slowly than usual. What could be wrong?
View 19 RepliesI have a '99 Chevy 2500 diesel truck. After driving it at highway speeds for more than 20 minutes and turning it off, it won't restart. The problem seems to be in the battery cable and is definitely heat-related. In cold weather or after a fairly short drive, all it takes is popping the hood to cool off the engine compartment, and waiting. If the engine and/or the weather is too hot, that can take an hour. Then it starts just fine. I've cleaned the terminals and made sure the connections are tight. Two mechanics have looked at it and were stumped.
View 1 RepliesAt around 70 mph when I am going down a hill the automatic transmission will shift down from overdrive into 3rd or even 2nd gear. It should stay in Overdrive. I have to tap the gas pedal to keep it in overdrive. They already looked at the TPS. Also, around 75 mph my ABS light goes on and stays on until I restart the car. Not sure if this is related. Just had a complete brake job.
View 19 RepliesIf I understand correctly my 2004 Expedition has the 4R75E transmission. We are experiencing a clunk upon acceleration when the truck downshifts from 4th to 2nd. I had the fluid & filter changed, flushed the transmission with cleaner. It still does it but not all the time. I turned OD off and I didn't notice the problem when shifting from 3 to 2.
View 1 RepliesI bought a 95 Explorer with a known bad transmission, rebuilt it (broken band and chipped intermediate apply piston), put it back in, and now it's acting odd.
It wants to start in third. I can manually start it in second (first rarely works), shift it to drive at about 30, and it's fine. It shifts into OD, locks the TC, and when given a bit of gas kicks down to second. It downshifts during deceleration, but once I come to a complete stop, it'll try to start in third again. The only transmission code it's giving is for incorrect first gear ratio, there is an off and on engine code for the EGR pressure sensor as well.

While towing a 9000 pound trailer at interstate speeds (75 to 80 in Wyoming), when pulling a hill, the truck downshifts to 4th gear, boost is about 18psi, eng and transmission temps in the 230F range, EGTs around 500C or 935F. RPM increases normally to 3000 then the turbo gets very loud and boost drops to about 10psi. The truck shifts to 5th gear, noise decreases but is still present, shifts to 6th and noise goes to normal after a couple seconds and boost builds normally.
This just started today. I have about 8000 miles towing this trailer and never had this before. I have about 350 miles until I'm home so I'm headed back out. Will play around with manual mode and see what it does. I also took a video of the gauges while this happens. Audio is difficult to discern. I will try to get better audio and post when I get home.
Our Pathfinder shakes side to side around 60mph and quits after 65 or 70 (We live in New Mexico and commute through Texas where speeds are much higher than back East). We have changed shocks, struts & mounts, tires, and alignments. Most of these have been changed multiple times over the years, especially tires.
We have been driving this way since May of 2005 (129,916 miles). We have TRIED to get it fixed. We have had it in shops all across the country (we travel a bit). We talk it up to people we meet who know cars. We have taken it to Nissan, with no results. NO ONE has solved the problem and we are out lots of money.
We are now at 205,000 miles. I would really like to get this fixed! We cannot afford to just buy a new car. Mechanics across the country have not solved this issue!
My daughter recently had me go for a ride in her car. 96 grand am 4 cyl. The car at highway speeds while making left turn the engine rpm raises. like the transmission is slipping or something. It only does it in a left hand turn above 55 mph. If you let off the gas pedal and the reapply it is normal until you steer into the turn again. only way to get it to not do it is to slow down. What would this be. transmission, wheel bearings, cv joints?

Problem "Stalls at idle and at hwy speed" sometimes starts right up and sometime will not start. Sometimes it will lose acceleration but engine will still be running and you can punch the gas and it will go again.
It has been in the shop for most of the last 2 months. Driven in 3 times and hauled in twice.
Low mileage 70,000 - has been great until now - serviced regularly.
Did get new fuel pump only about 10,000 miles ago do to starting problem but in that case it just did not start.
Independent shop replaced distributor cap, rotor, coil, fuel filter. No codes and couldn't duplicate problem.
Jeep dealer replaced fuel pump (they said wiring problem), O2 sensor, engine module no help, they asked us to pick up car because it ran fine. It stalled within 2 miles of shop.
We replaced gas cap just in case.
Limped back to shop to replace crank sensor as it was suggested several places. Ran fine for about 45 minutes then back to old tricks. Relays have been checked. Still at shop trying to trace problem. At least nobody is saying they can't duplicate problem as it now stalls all the time.
I wait for the glow plug to stop before attempting to start. Then it's like Aaron Tippin sings, "sometimes she runs, sometimes she don't". It turns over fine. When it's running, it runs good. But most times it won't start. The fuel is being stopped somewhere. The in tank pump is working..I can hear it when I turn on the key. What else can I check?

View 1 RepliesRecently the check engine light came on and coded out to the mass air flow sensor. I changed the sensor and cleared the fault code, but after doing so the car wouldn't start. After many failed attempts to start the motor, I disconnected the positive lead at the battery and reconnected it a few minutes later. The car started and ran smooth, however the check engine came back on and coded out to the mass air flow sensor again...
I let the car continue to idle and disconnected the lead at the sensor how the motor would react; it continued to run smooth....I then reinstalled the old air flow sensor and engine continued to run great...So with all this said, car runs great when check engine is on and code is not rest, however, car will not start upon clearing the code and resetting the light......is it safe to assume the computer is going bad and needs to be changed?
Just today AC started blowing air rapidly from the vents when I didn't have the AC on. The AC continued to run even after I had turned off the engine and took out the key. In fear of my battery dying I unplugged it but as soon as I plugged it back in to drive home from work it was the same thing. Where should I start?!

View 3 RepliesA while ago I had to lock up my brakes to prevent an accident. now my brakes are soft and spongy, going all the way to the floor and still not quite stopping. making abs type noise. also, i can press all the way down while standing still, with the same type noise.

1996 Chevy Lumina. Radiator fan won't run when engine is hot. Fan motor, relay and wiring check good. Relay coil has no ground but changing control module has no effect on problem. Engine temp sensor is new and reads good on resistance check. Also low coolant is lit on dash though that may be a separate problem.
View 9 RepliesI put new cheapest wiper blades from Auto Zone on my 1996 Impala SS when I bought it about 4 months ago. They are both quiet when it is pouring but if the rain is light the driver side wiper stutters like a wounded elephant, but the passenger side wiper is silent. What to do to fix this? Something to put on the windshield? Try a different brand, more expensive wiper?

View 1 RepliesWhile driving recently I experienced what felt like continued acceleration when I applied the brake. It was only a fleeting moment, but was scary nonetheless.
View 2 RepliesSo yesterday I drove my car to my friend's place, which is 6 miles away. Before the trip, the battery internal temperature (BT2) is around 80 F, with battery level 52%. After I arrived in my friend's place, BT2 is around 95F. I parked the car under the sun. Atmosphere temperature was around 80F outside. The battery level around that time was 65% (7 pips)
Three hours later, when I was leaving my friend's place, the BT2 was 114F! It was still like 80 F for atmosphere temperature.
