[QUOTE=Yotaoffroad27;2344286]I asked the same question myself. I wanted to know if I could run the old auto transmission from my truck. In short, No you wont be able to use the v6 tranny behind the 2uz, but yes they are both A340's. The F means 4x4 and the E means 2wd.
Toyota uses the A340 behind ALOT of its engines. From what I can tell it was in Lexus models, Tundra, Tacoma, 4runner, and the Sequoia. I even think its pretty much the same as the transmission found behind the 4.0L in the Jeeps. With that said, The bellhousings are ALL different, TQ converters, and input shafts are different too. I would imagine that the VB
and clutch pack counts are different too. Plus, depending on age, some A340s use a "detent cable" that runs up to the throttle body. My Tacoma had one when it was an auto. I dont think any Tundra's have this cable.
Btw, this has already been done, you just have to know where to look.
Thanks for your reply and info! I'm sorry; I've heard people dropping V8 tundras in tacos. I meant starting up a thread to install a V8 tundra engine into a taco. I just haven't found a complete online write up about swapping a tundra V8 into a taco until I ran across your thread.
Yeah, I know the 1U from Lexus have been dropped into a taco before. Smithers dropped one into his 95/96 taco. But after reading his write up, the 1U height wise is a little taller than the 3.4 V6 taco engines we have, but he had a body lift on his truck so it wasn't a problem and had to hack of some of the sheet metal to get the headers to fit. i don't want to install a body lift on my taco to get the 1U in and do the other stuff. Also, i read how 06tacov8 dropped in a 3U in his 06 taco. Furthermore, I've been on www.lextreme.com
. Did research on the swap.
So I believe the current tranny you're using in your taco is the W59 transmission right when you converted your taco from auto to stick? But, you stated that you're using an 1U bellhousing to mate with your 2U. How is that going to work? Just interested in your line of reasoning.
Yeah, my taco is a 03 double cab prerunner. Kept it auto because I didnt want to add the extra stuff required to have a manual. But I do miss driving a stick. My previous taco was a stick. I went the auto route with manual locking hubs because I didn't want to deal with the electronics and ECU. After seeing what you do with your V8 swap, I want to do the same thing with my taco, but I was wondering if this could be done with an auto so I don't have to make my truck a manual and then do the conversion. Just wanted to keep it simple. Haha. Sorry for all the questions. Thanks for starting up this write up! Good luck on the install! Looking forward to your future posts!
