1992 NISSAN SENTRA Power Train Problems

#1: I HAVE A NISSAN SENTRA 92 MODEL WITH AUTOMATIC TRANSMISSION. WHEN I FIRST START TO DRIVE IT WHEN ITS COLD, THE TRANSMISSION RUNS JUST FINE. IT UPSHIFTS NORMALLY AS IT SHOULD ALL THE WAY UP TO OVERDRIVE (4TH GEAR) FOR NORMAL HIGHWAY SPEED. HOWEVER, AFTER IVE DRIVEN IT FOR ABOUT 30 MINUTES IN STOP-&-GO TRAFFIC OR WHEN IT HAS BEEN DRIVEN AT HIGHWAY SPEEDS (40-65 MPH) & MADE SEVERAL STOPS IN TRAFFIC (I.E.: IT HAS WARMED-UP) THE TRANSMISSION WOULD FAIL TO UPSHIFT ABOVE THE 3RD & 4TH GEAR (OVERDRIVE). I WOULD HAVE TO REV THE ENGINE RPM UP TO AROUND 4,000 RPM TO ACCELERATE THE CAR TO ABOUT 40 MPH AND CONTINUE TO REV IT UP TO 5,000-6,000 RPM TO ACCELERATE IT FURTHER TO 45-60 MPH. I KNOW THIS IS NOT NORMAL FOR THIS CAR BECAUSE THE ENGINE HAS NEVER RUN THAT HIGH BEFORE TO REACH THOSE SPEEDS. I'VE ALWAYS DRIVEN THIS CAR WITH OVERDRIVE ENGAGED & I'VE NEVER TOWED ANYTHING WITH IT EVER. #2:  FRONT PASSENGER SIDE POWER WINDOW PLASTIC ASSEMBLY WHERE THE CABLE ATTACHES TO THE REGULATOR BROKE. *AK

WITHOUT WARNING THE 5TH GEAR "POPS"OUT OF GEAR AND INTO NEUTRAL, CAUSING THE ENGINE TO REV. THIS FIRST HAPPENED TO ME WHEN I WAS TRAVELING AT APPROXIMTELY 60 M.P.H., WITH THE CRUISE CONTROL ENGAGED. *AK

THE TRANSMISSION WON'T UPSHIFT FROM 1ST TO 2ND.

WHILE DRIVING IN 5TH GEAR AT APPROXIMATELY 65-70 MPH,TRANSMISSION DOWNSHIFTED. HIGH PITCHED WHINING OCCURRED. TRANSMISSION STARTED LEAKING FLUID. SEAL IS BROKEN. UNSURE IF TRANS HAS OTHER PROBLEMS. ONLY 53000 MILES ON CAR! ANY HELP?

BRAKES WHINE EVERY TIME PEDAL IS PRESSED. INTERIOR LIGHT STAYS ON IN AUTOMATIC MODE DUE TO DOOR BEING AJAR, LIGHT NOT TURNING OFF. SEAT BELTS IN BOTH FRONT SEATS AND ONE BACK SEATS DUE NOT STAY HOOKED. THEY COME UNDONE WHILE DRIVING. ALSO, PASSENGER SEAT DOES NOT ALWAYS LOCK. IT SLIDES WHEN SOMEONE SITS THERE AFTER THE SEAT HAS BEEN LOWERED TO ALLOW ACCESS TO BACK SEAT. SEAT BELT LIGHT DOES NOT ALWAYS TURN OFF, SOMETIMES TAKES A FEW MINUTES, SOMETIMES NEVER. ALSO, TRANS AXLE NOT IN ALL THE WAY, AND POWER STEERING RETURN LEAKS . MUFFLER BRACKETS STRETCHED,AND NOT SECURELY HOLDING MUFFLER (MUFFLER BROKE INTO TWO PIECES). CAR ONLY HAS APPX 54000 MILES ON IT, AND EVERYTHING SEEMS LIKE IT STARTING TO FALL APART. ANY HELP OR INFORMATION. *AK

WHEN DRIVING VEHICLE AT ANY SPEED, VEHICLE LOST POWER. WHEN USING THE CLUTCH AND TRYING TO GO INTO ANOTHER GEAR, THE VEHICLE WON'T PICK UP SPEED. *AK

TRANSMISSION FAILED RESULTING IN STICKING IN THIRD GEAR.

TRANSMISSION LURCHES FORWARD WHEN SHIFTERD FROM 1ST TO 2ND GEAR. (QCAW)

WHILE DRIVING TRANSMISSIOM POPS OUT OF FIFTH GEAR WHILE APPLYING GAS. THIS IS A MANUAL TRANSMISSION. *AK

WHILE DRIVING THE VEHICLE ON CRUISE CONTROL OR 5TH GEAR, THE GEAR WILL POP OUT, WHEN THE GEAR POPS OUT THE ENGINE WILL ROAR UP MAKING A NOISE, CONSUMER STATES THAT THEY HAVE CONTACTED THE DEALER, AND THE DEALER SAID THAT THE TRANSMISSION SHOULD BE OVERHAULED, DEALER ALSO TOLD CONSUMER THAT IT WAS OUT OF WARRANTY, THE CONSUMER SAID THAT THEY TOLD HER THAT THEY CAN NOT ADJUST THE LINKAGE ON NISSANS. *AK CONSUMER STATED THE STANDARD 5 SPEED ON VEHICLE SHOULD NOT BE ABLE TO JUMP OUT OF GEAR IF THE TRANSMISSION IS CONSTRUCTED CORRECTLY.*JB

TRANSMISSION MOUNT MADE OF ALUMINUM CASTING FAILED. PLEASE DESCRIBE DETAILS. TT
