Does it feel like it is missing 2nd (shifts from 1-3) or missing 3rd(shifts from 2 to 4th) with the overdrive light flashing. The 5r55w transmission is known for breaking the 3 gear band and the 2/5 band. Also it is known for wearing the band servo pin holes in the case for these bands. The 5r55w has no dipstick, you fill it thru the plug in the bottom of the pan.

The tranny wont shift up in drive from third at about 40 mph the tranny starts to hesitate stutter. already changed oil filter and speed solonoid


just by your description (detailed) id say it could go a few directions ??4 a cause, one way is the 40 mph is near the speed that overdrive is engaged (42 mph) these do sometimes have problems inside them (gears ) also the stutter you mention is sort of an indication that your torque converter didn't lock up or is locking/.unlocking this is an indication of a immanent torque converter failure , if car was made past 2001 then chances are good it has some kind of transmission control system that could log a fault to help you look for a cause like a faulty speed sensor or something , ck your codes !!

Cruise control notworking on a 2002 F150


cruise controls are controlled by the following switches and sensors
1 the switch itself
2-- the clutch pedal sensor or the VSS in the auto transmission
3 the brake sensor ---4-- the gear change switch or selector
5-- the engine speed sensor ( tacho)
6-- the road speed (VSS )
if 1 or a combination is not working or is outside parameters , the cruise control will not switch on
the road speed in a manual is set at around 20 mph and any less will not engage cruise control(CC)
changing gears in a manual will disengage CC
touching the clutch pedal will not allow engagement or will disengage CC
for some sensors run the fault codes

Transmission shifts hard


You don't give me much information to work with. However, 1st, look at the engine mounts. You may have a broken mount. This will make it feel like the transmission is shifting hard. Other than that, there is only a few things that will cause this. The speed sensor tells the computer when to shift the shift solenoids. It may not be "seeing" a quality signal. If this is the case, the speedometer will be bouncing too. Last idea is that it is skipping a gear. Starts in 1st, should go to 2nd at about 10 MPH. 3rd at 25 to 30 MPH. And, if you have a Overdrive transmission, it should go into overdrive at around 45 to 55 MPH. If it is skipping 2nd, it will engage 3rd at a high engine speed, and will feel like a sudden slam into gear. If this is true, your transmission needs some work. Hope this all helps. Good Luck.

Run the fault codes to see if the TCM ( transmission control module) is faulty or servos have failed . have a pressure test done on the box to check operating pressures for the clutch packs and bands.

Transmission not engaging 3rd or 4th gear


The symptoms & mileage is enough to tell
you it is time for a rebuild
Being a former police vehicle ,I would have
rebuilt the trans as soon as I got it,working okey
or not.
Forget advice that is typical unless you understand
the context the word was using in.

4 Wheel Grinds on Engage


make sure that your vehicle has a "on the go" 4wd operation
if not , you will have to all but stopped to get around the gear slashing
if you have "on the go " engagement , then is a problem in the synchro rings of the transfer case
take it to an accredited transmission specialist for a proper diagnosis

What is the o/d button on top of automatic gear stick for please


Over Drive..... Generally speaking, overdrive (OD) is the highest gear in the transmission. Overdrive allows the engine to operate at a lower rpm for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway. When it is switched on, an automatic transmission can shift into overdrive mode after a certain speed is reached (usually 70+ km/h [43+ mph] depending on the load). When it is off, the automatic transmission shifting is limited to the lower gears. For an automatic transmission, it is almost always best to select overdrive and allow the transmission to control engagement of the overdrive. (It may be necessary to switch it off if the vehicle is being operated in a mountainous area or when towing a trailer.) With a manual transmission, overdrive should usually be selected when the average speed is above 70 km/h (approx. 43 mph).

Should I keep overdrive on or off? also should keep ECT on or off?


Hello. Welcome to FixYa. I am Toyota Ed, and I will be assisting you today.

The Overdrive function allows the transmission to shift an extra time, sort of like selecting 5th gear in a 5 speed manual transmission. The Overdrive, when used, will save you gas, as the engine is no longer maintaining a high RPM at normal driving speed. Look at the tach whilst driving about 45 mph, and engage/disengage the OD. You will see the tach RPM raise when the OD is off.
More RPM = lower fuel mileage,

The ECT is a different circumstance. The ECT button is used primarily when you have a heavy load in the car, or are towing something. All the ECT button does, when it is engaged, is lengthen the shift points as the transmission upshifts. Normally, the transaxle will shift into 2nd gear at 18-21 mph. When the ECT is engaged, the transaxle will shift in the area of 22 -24 mph. In short, the ECT just makes the time to the 1-2 and the 2-3 upshift longer, to compensate for the additional load being carried/towed.

I hope my assistance answers your question.

Thanks for choosing FixYa today!

Overdrive factors


When the car is just cruising along at approx.50+ MPH push the O/D button. You should feel the gears change higher and if you have an RPM guage then it should drop as well to fewer RPMs. This would be normal driving conditions. O/D will not kick in until the last regular gear (3rd or 4th depending on model)  had been shifted into. O/D automatically kicks out when slowing down and the transmission shifts to a lower gear. Thus the O/D has no function at slower speeds/gears and does not need to be shifted ( on or off ) except in the very first example given here.

GM service engine code P1870/2000 GMC Sonoma 2.2 cylinder


you jave a biggie here.
here is some info
CIRCUIT DESCRIPTION
The Powertrain Control Module (PCM) monitors the difference between engine speed and transmission output speed. In D3 drive range with the TCC engaged, the engine speed should closely match the transmission output speed. In D4 drive range, with the TCC engaged, the TCC slip speed should be -20 to +60 RPM .

When the PCM detects excessive TCC slip when the TCC should be engaged, then DTC P1870 sets. DTC P1870 is a type B DTC.

CONDITIONS FOR RUNNING THE DTC
  • No TP sensor DTCs P0122 or P0123.
  • No VSS assembly DTCs P0502 or P0503.
  • No TCC solenoid valve DTC P0740.
  • No 1-2 SS valve DTC P0753.
  • No 2-3 SS valve DTC P0758.
  • No 3-2 SS valve assembly DTC P0785.
  • No TCC PWM solenoid valve DTC P1860.
  • The engine is not in fuel cutoff.
  • The engine torque is 40-400 lb ft .
  • The TP angle is 12-50% .
  • The vehicle speed is 56-112 km/h (35-70 mph ).
  • The speed ratio is 0.64-0.95 (the speed ratio is the engine speed divided by the transmission output speed).
  • The engine speed is 1500-3500 RPM .
  • The gear range is D4.
  • The commanded gear is not 1st gear
  • The TFT is between 20-130°C (68-266°F) .
  • The shift solenoid performance diagnostic counters are zero.
