Recently, I noticed that shifting from 2nd to 3rd feels a bit odd. I don't know exactly how to describe it, but it feels a lot more "rough" than shifting into any other gear. It doesn't exactly feel like its grinding though. It doesn't do this when shifting from 4th to 3rd, but occaisonally from 3rd to 4th. I'll probably find a mechanic that will check it out personally, but if anyone can provide some insight, thanks.

Go to a Mobil station and tell them you want a Synthetic Transmission Oil change. $39.95. Tell them to do the diff at the same time.

I've heard you shouldn't use synthetic oil in the supra's tranny. It's fine for the diff, though.

Red Line 75W90 Synthetic Gear Oil for the Differential.

Toyota T4 for the transmission.

I think that's only for the 6 speed, made by Getrag. The 5-speed are the same as the MKIII.

The MKIII 5 speed is a R154 gearbox the MKIV 5 speed is a W58. they are not the same at all.

The W58 was used in the MKIII NA, the R154 in the MKIII turbo. Although the W58 and R154 transmissions are different, except for some minor tweaking, the W58 is the same in both the MKIII and MKIV. The MKIV Supra six-speed uses a Getrag/Toyota 223, which should use only the approved lubricant, Dexron D21065, which is actually an ATF.
