FAQ - Source for Replacement AW4 Solenoids


New member
I see this question quite frequently, so I'm posting some info using some oft searched terms. I don't claim credit for finding this info as someone else posted it and I just scabbed it. The AW4 is made by Toyota and is also called A340 or A340E. A generic shift solenoid which works in this tranny is the "Rostra 52-9002". Googling should give you some vendors.

The cheapest source for the set of three I found was http://www.transmissionpartsusa.com/Solenoid_kit_A340E_1985_on_p/940-00094393a.htm. Part #940-00094393A at $160. (See http://www.naxja.org/forum/showthread.php?p=244408897#post244408897 for someone who just bought them.)

Another, slightly more expensive source for the set of three was http://www.makcotransmissionparts.com/97420K.html, or http://www.makcotransmissionparts.com/97425.html for just the lockup solenoid.

Sure bets the heck out of the dealer who wants $180 each.
