4 low

I just purchased a 09 Tacoma.Truck will go into 4high but will not go into 4 low and just beeps. I have seen to change the actuator on transfer is this true

 

Put it in 4 high.
Come to a complete stop.
Put transmission in neutral.
Now try to switch to 4 low.

 

Yes done all that many times after reading all the past threads.Its a manual so I have clutch in clutch out neutral etc etc .

 

Search for thread about disassembly and re-lubrication of the actuator.

 

Thank You

 

Clutch must be fully depressed and truck under 3mph to go into and out of 4 low.

Done it many times and it just won’t shift into low. Tried rolling. Clutch in,out stopped brake on off doesn’t go in

 

Does it beep as soon as you switch to low or after a bit?

 

Soon

 

Beeps steady

 

Are you holding the clutch in long enough for it to complete the shift? It can take a few seconds.

 

Yes

 

If it's never worked the previous owner may have messed with the Transfer Case Actuator and got it out of time.
Make sure your wires and vent hose are all connected at the Transfer Case Actuator, if they are then check your limit switch voltages and clitch switch input at the 4wd ECU as outlined in the thread I posted above and post your results.
