Typically the THM400 was the transmission of choice for these vehicles.

Actually the transmissions available in the 1989 suburban were the 700R4(1/2 ton) and 4L80(3/4 ton).

I have an 89 Suburban that only has a 3 speed (so its definitely not a 700R4 or 4L80E) and I know they had pretty much phased out the T350 at this time, the T400 was still used sporadically until around 91
