New Torque Converter & Trans Mods
Saturday, April 23, 2011 at 3:46PM My bad luck is sometimes paired to good luck. It's a push.
Michael at MV Automatics in Australia and I determined that the turbine had pulled loose inside of the original 4200 stall 1JZ MV converter (the grey one). Bad luck. Art in Pattaya happened to have a Percision Industries 1UZ 4000 stall billet race converter (the pink one). Good luck.

If you look closely you can see that the 1JZ and 1UZ torque converters are not the same. The 1UZ is thicker, and, more importantly, the input shaft from the transmission registers differently into the torque converter. I will not need the drive ring to mount it now.
The Precision Industries billet converter is a very nice piece.
This is the 1UZ front pump. The distance between the front pump and the shaft splines is just differnt enough [to the 1JZ splines] so that the splines will not engage. So, to properly index the splines to the torque converter I have to change the front pump over to the 1UZ; A340 transmissions are otherwise the same -- I am essentially making my old (non-electric) 1JZ transmission over to a new 1UZ transmission so I can use it with the new 1UZ race converter. Whew! But that's not all . . . .
There's your problem! Just kidding. It's good to be in a country that assembles Toyotas because there are ocasionally broken parts that come out of the containers. When this happens Toyota sells the broken parts as SCRAP! Lucky me! My man Art gets these brand new broken A340 transmissions from Toyota for a song and a dance and has passed his savings on to me. Lucky me!
Look closely at this pile of A340 parts - yep, brand new - really brand new 0 miles A340 parts. So, I will be putting 100% new internals into my trans case. Knock on wood . . . . "Lucky me."

This is my trans case with all new internal parts - with six (6) new clutches and eight (8) new steels. These are 100% new, unused parts.

Drove down to Art's shop in Pattaya with my friend Mike to pick up my virtually new A342 trans. What you are looking at here is my old 1JZ trans case with 100% new internals, all new electricals (senders and wiring), a 1UZ bell housing and Performance Industries 4000 stall torque converter. Nice.
Something you don't see every day: a brand new 1UZ flex plate & billet race torque converter.
It was a busy day! In addition to picking up my "new" transmission, I had to return the extra 1JZ trans to my friend Mac's shop (it is a somewhat rare case because it has the "slip yoke" tail housing) where we saw the new tall injectors on his road race car (photo below), and pick up Mikes Ford 200ci Ford block from a Thai machine shop for Art to mic. Mike is restoring a 1965 Mustang convertable here in Thailand. Then we went to the body shop that is restoring his '65 Mustang to drop off the Ford block. I ended the day at my race track shop unloading the trans and cleaning the pick-up bed of spilled trans fluid (very hard to get out). I will reinstall the trans this week . . . but I will have to get an electrician to sort the wiring 100% before I try to test it.
Mac's road racer . . . . he shifts at 9500rpm . . . so longer injectors are good. These are 100% made in Thailand.
