The SB or SSV – What’s The Difference?
Often, DTCs related to the solenoid switch valve (SSV) in any 41TE or 42LE transmission are misinterpreted as a problematic solenoid body (SB). This may be attributed to the use of the word “solenoid” in the code definition. Code 37 is the solenoid switch valve stuck in the TCC position, and 47 is the solenoid switch valve stuck in the L/R position. Either of these will place the transmission in “limp mode.” The solenoid switch valve is not in the solenoid body but in the valve body (see Figure 1).
