Are you sure the TV ( trans shift cable at the throttle valve) cable is correctly adjusted?? Without line pressure readings, I can only guess that the D3/Part throttle check ball is missing, if it is a trans problem
If the TV is correct, I am assuming that the TV cable is pulled tight at WOT.
Did you check the throttle (ACCEL) cable to be sure that the carb goes wide open when your accel pedal is on the floor?? This must be done with someone in the car and a second person looking at the carb. Without doing this, you do not know if you have WOT. Without WOT, the trans will not de-tent and shift down.

Is it normal for the revs to stay up when changing gear in a 2002 4x4 3.0L turbo diesel navara?


do they revs drop off when taking pressure off accelerator pedal when out of gear? if only staying high during gear change it would suggest a worn clutch friction/pressure plate so the engine isn't slowing down when clutch is depressed .I'd also have the OBD codes read to see if there is a sensor/switch at fault , but sounds like the clutch to me

DEFINITE LURCH IN 1ST AND 2ND GEAR,


This may apply. ...............................

Carry out the adaptation drive cycle road test:

Note: This process must be carried out in normal mode (not sports mode). On a flat road, the transmission fluid temperature must be above 60° C (140° f) and below 100° C (212° f) (vehicle at normal operating temperature will ensure that the transmission fluid temperature is above 60° C (140° f)).
9. Accelerate from rest with light throttle (do not exceed the upper rev limit in appendix 1). 1-2, 2-3, 3-4 shifts must occur with engine speed between the following limits:.
Note: Do not move the accelerator pedal during shifts.

• 3.0L VIN ALL 1800 - 2000 rpm
• 4.2L N/A Prior VIN M96321 1450 - 1600 rpm
• 4.2L N/A From VIN M963221550 - 1700 rpm

10. Continue to accelerate gently to 50 mph (80 km/h) so that transmission shifts into 5th gear.
11. Go into overrun and let the transmission shift down into 4th gear without braking.
12. Brake gently to a standstill and hold footbrake on for at least 15 seconds.
13. This process should be carried out at least five times.

I have low exceleration when i take off


Only recently has my 97 Honda Passport been acting like the transmission slips...I'll be in Drive and the revs jump from 2 to 5 or 6; I'll drop it to 3, and it settles down. Last week, I was in Drive, then went to 3...then back to Drive and it jumped...and the Check Trans light came on.

1992 GMC Suburban not shifting into OD, Transmission Modulator?


The shift down linkage on the carburetor below the gas pedal cable might need to be adjusted to increase the hydraulic pressure on the internal clutch plates in the transmission it shows you how to do that in a car manual.

Cannot accelerate past 40 mph


Hi,
Does it rev ok? If your motor revs high but still doesn't go fast, you could be having a transmission issue, where it's not shifting into high gear... I'm assuming it's an automatic.
I hope this gets you on track... Good luck.

1997 Dodge Ram 1500 automatic transmission won't shift out of 1st


It sounds like your speed sensor may have gone bad.
If you can get it to Auto Zone they can scan the truck for you and let you know if it is the speed sensor. Auto Zone scan for free and and may have the parts right there.
The part is  not that hard to replace and they can give you the instructions on how to do it your self. The only other thing is to take it to a transmission shop and have them scan it and repaire it.
Just be careful that they try not to sell you the whole transmission and not just the sensor if that's what it is.
Good luck and hope this help. Be careful that you do not burn out the transmission as it will not shift, You may have to change the transmission fluid and filter if there already burn. The speed sensor is on the out side of the transmission on the driver's side. Check the wire harness and clips too.
