 These recommendations do not cover all possibilities. They are some things to check before you have your transmission rebuilt. Always check transmission fluid level first. Always run a scanner on any computer controlled transmission. On modulated transmissions make sure they have enough vacuum.

 The transmissions above are front wheel drive 4 speed automatic transmissions. They are computer and throttle pressure controlled.  Common symptoms are transmission shifting erratic, slipping or not shifting at all. Also the check engine light can come on.

External sensors like the throttle position sensor, vehicle speed sensor or output speed sensor quite often go bad, causing these symptoms. Check the throttle pressure cable that goes from your transmission to your carburetor or throttle body depending on the configuration of your engine. Always run a scanner to see if a sensor is causing your problem. Check the shift solenoids that attach to the valve body, sometimes they can go bad.

Many of the transmissions above have separate fill for the trans fluid and the differential, so be care full! I see a lot of differentials burn up from lack of lube. Then the transmissions need to be rebuilt. On most Toyotas, they have a diagnostic box you can retrieve codes with. The location of this box should be in your owners manual.

 The transmissions above are rear wheel drive 4 speed automatic transmissions. They are computer and throttle pressure controlled.  Common symptoms are transmission shifting erratic, slipping or not shifting at all. 

Always check your throttle pressure cable adjustment and see if there are any diagnostic trouble codes in the computer causing the problem. On most Toyotas they have a diagnostic box you can retrieve codes with. The location of this box should be in your owners manual.

 The transmissions above are rear wheel drive 4 speed automatics and shift timing is controlled by the computer and a throttle pressure cable that connects from the transmission to the carburetor or throttle body.  Always check these items first before your purchase a transmission. Common symptoms are transmission shifting erratic, slipping or not shifting at all. Also the check engine light can come on. Always check your throttle pressure cable adjustment and see if there are any diagnostic trouble codes in the computer causing the problem. On most Toyotas they have a diagnostic box you can retrieve codes with. The location of this box should be in your owners manual.
Make sure your clutch fan on the front of the motor is not starting to seize up.  This causes the engine to sound unusually loud almost like the transmission is not shifting into 4th gear.

131L / 132L
 The transmissions above are front wheel drive, 3 speed automatics.  Common problems are: The transmission shifts soft and early. It shifts hard and late, or not at all.

On this model you have throttle pressure cable that goes from your transmission to your carburetor or throttle body depending on the configuration of your engine. This controls the shift points and shift firmness. Check your throttle pressure cable adjustment to see if it is causing the problems. 

If you have a style with shift solenoids always check them. You can also see if there are any diagnostic trouble codes in the computer causing the problem.
