My '95 LS had a 2 way rocker switch down by the hand brake. One way was "hold" which I believe forced 2nd as the lowest gear to reduce wheel spin during acceleration on slick surfaces. The other was power which I guess increases the shift rpm's. I didn't notice much difference unless I was really on the throttle and towing. It was helpful to keep it out of OD towing on the hwy. According to Lee I guess none of that would apply to the '94.

However - when cold it would rev pretty high before shifting, and settle down after a few minutes. I don't know if that would apply to the hydraulically controlled trans or not.

Aren't main seals and crankshaft seals the same thing?

One thing I'd look closely at is the dreaded blue exhaust (leaking valve stem seals) when taking off after idling for a while. It's an expensive repair to have done, and a real pain to do yourself.

I got 3K out of the '95 (206k) on trade, it was in pretty dang good shape though for the year/mileage.

For a decent 94 with 160ish 2k sounds pretty good.
