Im installing a new engine & torque converter in my girlfriends 4runner (93 V6) that I got her for the snow. I bought a new one from the auto parts store, and after a while of trying to install it I realized that the input shaft is 26 splines and the torque converter is 20 splines! From the door code the 4runner has the A340 transmission. But when I go to buy a torque converter from the auto parts stores, they only have the 20 spline. I managed to find 26 spline converters online for the A340, but I want to make sure I get the correct one. If someone could point me in the right direction that would be great, thanks!

 

what store did you go to? it's not uncommon for stores to inventory the wrong part. had to go back twice trying to get motor mounts when i was repairing my '94 subaru wagon. it was an "in between" year model when factory parts were being redesigned

as well, there is another letter after the A340. should be perhaps an "H"? did you specify that to the store attendant? no expert on these transmission, but it could have some bearing

 

I ended up having them order it a second time, because I thought they ordered it for the wrong transmission the first time, because it didnt fit. I made sure the second time that it specified as the A340H, which is the one in the 4runner according to the door code. And the second time is when I discovered the spline problem. I went back to have them order the 26 spline and it was not available. This was O'Reilly auto parts. I believe this is the one I need but I'm not 100% sure.
