He said he would let me have it for the cost of shipping. Why does it look different from you old sc3 w58?
I realized it was you after posting, lol. Glad you found another option.

Toyota used enclosed housing extensions in their W58's for the SC from '92-'94 and for the R154's in the Soarer from '91-'93. After those model years the tripod design was used across the board for either manual transmission. Supra MKIV NA's all used tripod designs from the start-- exactly the same W58 as you are looking to buy.

You can cut the transmission tunnel or you can go to the trouble of swapping in a Supra 6-speed tunnel for use with that tripod trans. Most people just modify their existing tunnel.

^^ Exactly. Cali108, even the early W58 I was selling would have required you to cut you trans tunnel because you have an SC400. It also needed a "swan" shifter rather than a straight shifter but I've found the SS V3 short shifter to work perfectly on those older extended W58/R154's. I'm using one right now in my '93 SC300 5-speed with the early style tunnel opening and it's very close to where it should be. Pricey, but it would have been a good shifter option for you prior to your finding this tripod 5-speed.

The SC/Soarer manual shift boot location never changed throughout the model cycle, just the way the 5-speed transmissions got the shifter into that spot.

Kahn, you are right on the synchros. I have to shift on first before I go to reverse, or everyone will hear the horrible grinding sound... very embarrasing when it happens. Can you please PM me info about your R154 rebuild?
