Start with the simple and check all your fuses. Sounds like the power on the data port has no power to it and is causing your code reader does not power up to read any codes.

Good luck and keep us posted.

use a scanner that is capable to read transmission codes and data, if there is no codes, check the pressure from the transmission test ports, because is leaking pressure internally.

I recently had work done to my transmission , why will it now go forward , but not in reverse ?


Bring it back where you had it worked on. There is likely a defect in the work that was done. There are relays inside the transmission on some newer cars and that connection may have been damaged or not plugged in.

The fuel pressure sounds too low. Is it multi-port injection? Check the fuel pressure against your specs for the car and engine. MPFI systems usually require 40-50 psi.

Transmission will not shift into high gear


That chocolate cottage cheese may have been transmission fluid mixed in with your engine coolant (transmission cooler in radiator ruptured), which means you could have been getting engine coolant in the transmission. What does the fluid on your transmission dipstick look like? If the transmission fluid is contaminated, it could cause a lot of problems in the transmission. If you suspect this, have a transmission shop check it out. Just changing the transmission fluid will not correct this, as there will be a lot of fluid that doesn't drain out - in the torque converter, valve body, and all the passages and clutches.

Transmission will not shift into high gear


sounds like the auto oil coolong pipes popped a leak in the radiator

do the auto service and fit the parts
if oil and coolant haven't mixed in the auto itself
over drive clutch set may need a new kit fitted

drive it a bit and see what happens

Nissan Hardbody timing issue


The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exceptions to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

My speedometre stoped working in my suburban 2001, everything else works fine


01 Suburban has an electronic speedo which works by way of a speed sending unit on the tail end of the driver's side of the transmission. Replace that speed sending unit if there is any transmission fluid coming out of the plug entrance (where the wires plug into the sensor). Could also be a speed sensor mounted on the top of the differential, but less likely. Do get it fixed because either one of these could cause shifting problems in the transmission... Ugly.
