I would want to know the answer for this as well, tried to search but didn't find anything.

 

I'm sure a 6l80 could be made to work. Expect to spend some serious coin though.

 

6l80E with paddle shifters would be nice

 

Verrrrrrrrryyyyyy nice, indeed!

I'm sure a 6l80 could be made to work. Expect to spend some serious coin though.

I saw reference to it holding only 430 ft-lb torque! That won't do - did I miss something. And prices were quite high - I saw a quote for $4700 shipped, no install.:crying:

 

The IS300 uses a 5 speed transmission but from every report it's weaker than the 4 speed behind 2jz-gtes.

 

I wonder if some trans reprogramming might help?: http://redhardsupra.blogspot.com/2005/08/road-racing-automatic.html

 

Well, it won't give me another gear or two, although the idea is good for a track-only car.

 

I've been thinking about a 6r80 from the new 5.0's
They are good for putting a 3800lb mustang into the low 8's unmodified. Ford rates these autos in stock form for 800lb ft of torque. Some of the new 5.0 guys have been putting 900-1000 lb ft thru them no problem.

 

Anyone know anyone that has done this in a MKIV?? I know everything I read here is an upgrade for drag or street racing, but those won't work for me.

 

I don't know much...well...anything about it, but this built Aristo has an SP400:

I don't know much...well...anything about it, but this built Aristo has an SP400:

...which is a 3-speed transmission

 

AB60e Toyota tundra 6 speed trans would be cool and are very well built.

 

The new 2013 mustangs have paddle shifters with the automatics too. I honestly think it would be a better option than the tundra transmission. I've heard of failures with the tundras with the Trd supercharger. 504 Hp and 550 lb ft at the crank supercharged. If I was gonna spend the coin and time putting a 6 speed auto in a supra and wanted paddle shifters I would get one from the 2013 mustang 5.0 the transmission is already strong as hell. Easily capable of 800 lbft of torque unmodified. As far as price wise I have no idea but at least you wouldn't have to worry about building the transmission.

 

well that 6r80 out of the ford f150 and mustang sells on ebay for about 1500 sooo if you can figure a way to control it i supose it wouldnt be a bad option if you could make it fit and work out the torque converter and bell housing adapter

 

Where there is a will there Is a way.
Would pro-efi be able to control it? It really would be a sweet trans with the paddle shifters.

1500$ isn't bad at all! Were they new or used?
I'm not sure if the ones from the 5.0 and the f-150's are identical. Knowing ford and their modular mindset they should be the same

 

One of the fast-shifting DCT's could be awesome for performance.

I work at a trans shop and all ford trans are not built very good. it's there case and electronics that make them bad.. Cheap stuff. But I haven't gotten my hands on there new trans yet. As for the tundra trans it's very strong only problem they have is there plastic accumulators that go bad...but nothing a billet ones won't fix and cheap fix.

 

I’m pushing over 500HP in 6-speed 5.7 Tundra and it’s covered by my 130K Toyota warrantee, no issues! :bigok:

 

huh?

 

I hope someone looks into this and gets it going. Would love to see either of these transmissions retrofitted.

 

Ford autos of yesteryear were a joke. From what I've seen the new mustang auto is a beast though. I think that would be the best route.

 

Well my transmission is on its last leg.. no 4th no OD anymore... I'll start looking up the tundra transmission prices and see whats up..

 

You could also look into the 6-speed auto that's in the Lexus LS430 (2004-2006, only). I have a 2006 LS430, and in comparison to the stock A340E that I have here, and my stock GS300 trans that I've serviced in the past - it looks like it's built like a brick shithouse. They're cheaper on EBAY, too. I've seen them for around $900-$1600.

 

so would the 7 speed dual clutch getrag tranny fit into the supra??? what else would have to modified?

 

I don't know, it might be a pipe dream.

Edit: this has some wiring info on the bmw m3 7speed dct:
http://www.m3post.com/forums/attachment.php?attachmentid=587904&d=1317583307


The Lexus IS-F 8 speed auto might be easier on the wiring end and also claims very fast shifts for an auto.

Edit: I see a couple up for auction.

 

damn an IS-F tranny....god knows the tag on that.

 

I have never once seen an automatic at the track. How does that even work with gear selection in braking zones before a turn/setting up for a corner? Doesn't your car just upshift itself as you are slowing ?

 

well thats why for circuit you would usually see a 6 speed Supra and in the 1/4 mile you would more likely see an auto.

 

TCI has a 6 speed auto which appears to be a modified 4L80E.

That is impressive - with a price to match!
BTW, Jim - what do you have in the red MKIV?

 

^ Awesome.
