Ahh I see. There won't be any drifting in my truck. I have 20's going onto it, with a bd and bags. The whole works.

 

Don't tell me you can't drift an auto... cause I do. It has to be built right. Anyways... if you have a ge... stick with ge parts. If the ecu your running is a ge, i dont think it will talk to a gte trans ecu. And to swap a gte ecu in place of your ge ecu will take way more work and related parts than you want to deal with. The wiring MIGHT be the same between a ge and gte trans as far as plugs go.... but don't quote me on it as I only deal with gte transmissions. Ill try to answer anything else ya might need help with...

 

I drifted my automatic 22re A43D open diff..


but it was horrible.


automatics rob horsepower at the same time are self destructing. they run on heat and heat destroys transmissions. I hate dealing with ATF and just the fact that auto's are heavier too...

 

Well I don't feel like relocating the clutch so I can tuck my 20's, so auto is the direction I will be going. Plus I honestly won't be building this truck to be drifting and racing around. Low and slow

 

That's exactly what I said. But then I actually got behind the wheel and dam it handled good! LOL needless to say I had to push the boundaries.

 

manuals feel more connected to the road...




the A340E's are electronic I believe, shifts better than the hydraulic A43D anyway!

 

When my cressida was auto, I will admit it was one of the better autos I've driven. didn't hold gears too high, wasn't too eager to downshift. but put your foot down and it was firm and did what I expected it to. Well matched to the engine torque curve. side note: The only thing electronic about it is shift timing. the 4 shift solenoids are the only thing controlled by the computer.

FYI the supra and cressida AT controller is the ECU, there's no separate computer. the late '87 and '88 MX73, however, did have a separate TCU and ran the A340 (prior to this ran the A43). I've swapped a MX83 A340 into an 87 MX73 and it worked but threw a code. never checked the code so I dunno what it was but it does work...might be something to look into. While we're on the subject of mix n match, I doubt the supra computer will care if it's controlling a turbo or n/a trans.

Another thing to look into is the supra stick AT controller. SSv4 It sounds awesome but I've never tried it.

BTW what ECU and induction plans do you have? the OE N/A computer needs to be piggybacked heavily to run even a few psi (mainly because the AFM maxes out real quick) which turns into a nightmare fast. Turbo ECU works but you'll have to swap out the distributor for CPS and coilpacks as well as some other parts because of plug compatability.

 

I don't really plan on running a turbo in the near future but maybe eventually. Right now I just need to figure out what I will be putting in it so I can start building motor mounts and trans crossmember, and so I can figure out where I need to build the 3 link. I'm thinking about going ahead on the 3 link and then just getting a drive shaft built specificly for it. There is a shop here in Vegas that is supposed to be reasonable. I figure I will build the 3 link, then notch the frame. Or should I notch then 3 link?

 

Probably notch first. It would give you the chance to expirement with all the heights the axle will be at once it is done. Because you want to find a good angle for the pinion and driveshaft. Sometimes you can get bad driveline vibrations if it's not aligned right.

 

Good idea. Thanks a ton!
