Saturn sl1 1999 transmission computer
on that model the trans computer is built into the engine computer there scan tool will not get into that part the code they are reading is just a code stating there is a trans code what problem are you having?
Car over heating
Not sure what you are asking.The engine temp sensor tells the computer when the cooling fan is needed and the computer grounds the fan relay to make it run.You could have a problem with the thermostat or the radiator could be low on coolant.
Diag codes for trouble shooting po141,po404,po440
Code 141 is the O2 (oxygen sensor) gone bad, needs replacing.Code 440, 442 and 445 are all in the EES (Evaporative Emission System). They are leaks in the PCM (Powertrain Control Module). It tests this system when there is about one fourth tank of gas left.This system controls fumes from the fuel by storing it in a vapor canister until they can be burned off. This system has several parts in it. You have the solenoid (which is a vent valve and a purge valve), fuel tank, a vapor canister, and you have lines coming from engine vacuum port, going to the vent valve. But you may want to check your gas cap. This is the culprit most of the time. As we take it off and on, it can cause leaks. This is also the cheapest solution. You'll have to clear your code with an OBD scan tool, to see if it was repaired by replacing your gas cap.Also older vehicles can have a leak around the fuel filler neck where the gas cap attaches to is a seal and it could have gone bad.A lot of times that seal is leaking around that filler neck. So more likely than not, it is leaking and/or gas cap needs replacing.A 403, 404,405 are in the EGR System. 401 and 402 are the EGR valve.You will get these codes because the PCM has sent them. It will send them to test the system as part of a self-diagnostic test and the other reason it sends it is because it wants to monitor the EGR system through everyday, normal operations.This is what is known as PCM command. It is looking for correct signal of the wires to make sure they are working right from the solenoids in the EGR valve.There is a problem in the EGR system that needs fixing. Sometimes replacing the EGR valve will fix the problem, but before you go out buying a lot of parts for your car, have a mechanic shop test the EGR system.Good luck.
I have no revers, sometimes very very little 1999 saturn sl
Check the line pressures, and if low, suspect a worn bore on the pressure regulator. Check for a loose nut on the main shaft. Air check the 2nd oil passage, and if losing pressure, remove the side cover and check for a loose main shaft nut. If a loose nut on the mainshaft is not the problem, Your going to need to pull the transmission and have it rebuilt.
