Hmm, I stand corrected. I guess I should have researched before I opened my mouth. *lol*
I thought maybe it was the difference between the WC and non-WC T-5's but it has to do with the 3.97 first gear in the 4-cyl boxes. I'm kind of bummed now that I know this since I suspect I need a new bearing retainer for the transmission in my '93.
