And... the final nod goes to reliability over parts matching. Jim

Substitution Sad to say, I had a great deal of trouble using the small pins that this connector body uses. They have the same P/N as the ones used by the main transmission connector (AA80E) but even after removing the inside cap getting the pins to lock in was difficult and they didn't look...

Thanks George, that helped. I was able to find the truncated part number on the connector, add the prefix from the book and find it with a Google search. About $7.50 ea so I ordered 3. One to dissect, one to screw up, and one to get right. Jim

Nobody knows?

Hi again everyone, good to be back. I could use a part number and maybe a source if anyone has them, for the shift selector switch's connector plug on the wiring harness. I know they are available, I bought one a couple years back but I should have bought three. It has those ultra miniaturized...

What has to be done to use the stock ECM from the 2001-2005 SC430 in a different car? I've heard there's something with the steering column, no doubt having to do with the key which I'm guessing has an embedded chip. Does anyone have more information on this? Thanks, Jim

Does the ring gear on the UZ engines sit in the same place as the ring gear on the UR engines? Jim

Back about the 40's and earlier it was common to use gasoline to start diesel engines, particularly in tractors and then once running switch to diesel, in fact they often came equipped with an extra, smaller fuel tank to put the gasoline in. Of course compression was lower and the components...

They definitely use a larger bellhousing. I think the backspacing to the flex plate is different too but I'm trying to confirm that. (13mm rather than about 22mm) The torque converter bolt size and pattern are both larger. Used common 10mm rather than the almost impossible to find 9mm converter...

Couldn't tell anything from the contact patterns. But the pump drive notches look very similar so I'm guessing around 1/8" and maybe a little more should work out fine. The AA80E is used behind the UR series engines. I have it on the bench next to an A650E which was behind the UZ series. The...

Interesting response. I know that with the typical American automatics 3/16" is standard. This is the distance that the converter will move rearward into the transmission after it is unbolted from the flex plate, and it is to allow for swelling of the converter under high rpm operation. I will...

How much end play (or movement) should the torque converter have when unbolted from the flex plate? This is the AA80E transmission used in the 2008 IS-F but I'd imagine it'd be the same as the 6 and 5 speeds. Jim

Thermactor, I don't know if it'll keep up with your LS400 or not, but if 315/35-17's, a posi, an 8 speed and roughly 1 hp per 5 lbs of vehicle weight will get the job done then I just might have a shot at it. I suppose we can give it a go later on when we get both cars back into action...

That might not be a bad thing, I'm very impressed with the development that's been done on the IS-F. But for that to happen I'm afraid someone's going to have to offer me a job that will pay for the toys. As it stands right now, old technology is about all my budget will stand. This new toy (the...

Thanks, looks like he used a PCS controller but they do not support anything beyond the A340 and their controller does not have enough outputs to support the AA80E, or the A650E for that matter, and when I contacted them awhile back they weren't interested in the A650E. I know James Murray...

I made a very "irregular" deal on this tranny which will make comparisons difficult as it started out as a purchase of a 6 speed which due to a misunderstanding ended up being a 5 speed, and in the end created a discount on the 8 speed and what I ended up with was the 5 speed and the 8 speed...

From the Lexus parts desk, the vin number (from the metal tag on the side of the transmission case) identifies the car as a 2008 IS-F, so this is indeed the transmission it is supposed to be. Jim

I just had a transmission delivered, how can I verify that it is the 8 speed automatic out of the IS-F as promised? I have copied the identifying numbers: 35010-53110 (I believe this is the part number) 08CLA02414 JTHBP 2624 85001996 and then there's a matrix of 5 digit alphanumeric...

It's OK, I get that a lot. Usually because I'm trying to do something off the beaten path. But hey, any help is good! Jim

The answer is that they are not the same. Among the changes made to the LS460's 8 speed transmission was the use of a high rate linear solenoid to enable lightning fast gear changes so the crucial question of whether or not the LS460's transmission will shift as fast as that of the IS-F is, no...
