t-56 tranny
 

i have a supra 5 speed that im puting a t-60 on. its a built block and im worried that im gana break the tranny. so instead of paying an ungodly amout for a getrag 6 speed i want to get the t-56 6 speed with the adaptor plate. i wanted to know how many supras have done that?

What's a T-56? Is that an MKIII tranny?

For what it's worth, you should be able to pick up a getrag v160 6spd for about $2k if you shop around. Imho $2k for a 6spd tranny that will hold 1500rwhp is a great deal... *shrug* :dunno:

T56
 

T-56 was in the viper,camaro,trans am,corvette and last but not least the 99+ cobras for sure. I was looking into this my self, cause they are stoped making Getrag 6 speeds i heard and there is no lack of parts for a T-56. Let me know how it gos.

If it's the supra turbo transmission that you already have, just get it rebuilt and you're good to go. These transmissions can take a pretty good beating. It'll cost less in the end to get the current one rebuilt. You'll need a custom bellhousing, custom driveshaft, and custom mounts for the T-56 which will cost $$$.

Yeah but finding parts for the Getreg . that might be a problem in a year or two. On the second note , the supra TT Auto Tranny isnt that strong. i've Blone them up at 425 hp one held to 475 for a week , The hole point of the swap would be the mass Aftermarket for the T-56.

my two cents

Yes you are correct. I was refering to the 5 speed tranny tho. My mistake. I didn't specify. The Supra auto trannies aren't that strong. One would need to have it built.

Parts for the 5 speed
 

Pthat would be interesting to know about though, Do they sell Built 5 speed getregs?

Nope, only 6 speeds. The 5 speed MKIV supra is a beefed up W58 tranny that the nonturbo MKIII supras used. The R154 (the one I was refering to) is pretty damn strong. I'd guess it can hold about 800+ ft/lbs of torque when it's rebuilt.
