Using rubber hose on cooler line is generally a temporary repair. but if you need to use it put several clamps on and locate screw parts 180 degrees from adjacent clamp. (sometimes slightly flairing the end of the metal line very slightly will keep hose from sliding off.)

Automatic drives fine yet gears won't shift up steep hills


depending on the type of transmission, they usually use throttle pressure to determine down shift older cars use a cable attached to the carb or throttle body, newer cars use the tps signal to the transmission comp. to determine downshift points under load

When i start my car and go to put it in gear it wont move.


When you say rocky spot, what do you mean? If you mean there were rocks in the roadway, you could have put a small hole in the transmission pan which leaked all the fluid out of it. First thing I would do is check the fluid level on the transmission dipstick and look for leaks on the ground under the car.

What could cause the car to stutter when under load going up hill.


It sounds to me like a passing gear issue. Or even and Over Drive issue. Try this to find out. When you put the car in gear, instead of O/D, try regular drive. If you have a push button O/D then deactivate it. If you only have Drive, then try shifting into 3. Run the car up to the same speeds you were having problems with. If you don't have the issues with the higher RPM's then it is an Overdrive/Highway gear issue. If it still stutters, then it could be a fuel delivery issue. Good luck.

1998 Grand Marquis. Start goods. idols low. put in gear, stalls out. Changed fuel filter & had injectors serviced. Problem remains. Could it be the Transmission modulator valve?


I would check the operation of the idle speed control valve, it is what changes the idle speed when a load like the transmission is put on the engine, without it the engine will idle slow and stall out, this is even more apparent when reverse gear is selected or drive or the AC is tuned on. The ISC valve is located on the side of the throttle body top of upper intake manifold. Below is a picture of the ISC (idle speed control valve)

When car is in drive it will not shift right coming out of first gear. it will **** really hard then shift.


Check vacuum hose to modulator on the transmission. One that is leaking will cause it not to shift out of first. Open hood and look for it at the front of transmission. One can shift it manually by putting in first then shift to next gear.

Its 2 wheel drive, but the transmission won't shift unless you manuallyl put the gear shifter in low then work your way up to get the gears to change. The gears work fine it just won't change on its on. If...


Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under-hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Good luck and keep me posted, there are other things but these things mentioned seam like what you described.

4L 60E - 2001 k1500 will not shift into 3-4. Oil is not burn't and stifts great into1-2


  • No 3rd or 4th gear: “3-4” clutches are worn out. R&R. The car is safe to drive (in 2) until you can get it fixed.
  • Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.
  • No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : Shift A solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.
Check to see if your transmission is in the limp mode, which would only give you 2nd, 3rd and reverse gears. No 1st or 4th gear.

Sheift lock


The term "shift lock" is the system that is in place to prevent the vehicle from being shifted out of Park into Reverse or Drive WITHOUT having the driver's foot firmly on the brake pedal. The brake light switch on the brake pedal closes a circuit that energizes a solenoid under the shifter. When the brake is applied, and the solenoid is energized, the shift lever is no longer "locked", and can be moved to the desired position.
The idea here stems from a phenonomon several years ago that dealt with the issue of "Sudden Intended Acceleration". What was happening here was, for some unknown reason, engines started developing high RPMS for no reason, and several accisents were reported due to this issue. The vehicle would accelerate "unintendedly", when putting into drive or reverse, and could hit something.
