Supra TT automatics have 3.769
Supra TT 6 speeds have 3.13
The supra TT automatic carrier is bolt in. The supra TT 6 speed is not.
All 6 speed supras were LSD. Not all supra TT automatics where. Confusing and many do NOT know what they have.

Nope. 6 speeds were turbo only and had a 3.133 ratio
The NON turbo 5 speeds are 4.272 for 1993-1996 and then 4.083 for 1997-1998
The 6 speed turbos used the worm style LSD in all year models.
The automatic turbo used worm style LSD for 93-96 years and then went to the helical style LSD for 97-98 and LSD was an OPTION on 97-98 turbo automatics.
Non-turbo supras also had OPTIONAL(rare) LSD and used a worm style LSD model years 93-96 and then helical style in 97-98.

Which is better for the GS400? worm style or helical style? and why?

So, a used automatic TT worm style would be older and possibly more worn than any used helical style.
If you can find either one in good condition I would get it. That said MANY 1997-1998 turbo supra owners are unaware if their automatic actually has a torsen (helical for these years). Many have basic open differentials. Some sell these as torsen when in fact they may not be. The ONLY way I am aware of to make a positive determination is OPEN IT UP and LOOK. I actually bought one a few years back and had this problem. The seller was POSITIVE it was a torsen and initially accused me of not knowing the difference and then lying. He finally believed me and refunded my money.
