Just need to bounce some thoughts off some gearheads that know this thing inside & out (at least more than I do heh).
From what I've gathered and found, I have the 4L60E transmission ('94 s10 blazer 'w' 4.3l CPI). This trans is electronically controlled (no kickdown vacuum, etc). It decides when to shift based upon the vehicle speed; fed by the vehicle speed sensor on the transmission. If the PCM receives no data from the VSS, the speedometer will not register any speeds and the ABS will not function (throwing an ABS light but no SES light).
With me so far? Am I correct in my knowledge/findings?
Anyway, here's whats going on. My truck's (94 s10 'w' blazer) speedometer, odometer, and trip odometer are not functioning. Additionally, the ABS light is lit. There is no SES light, just the ABS. When driving, it doesn't seem to shift out of 2nd gear (into 'D' or 'OD', etc). Reverse is fine, and if I mash the gas it downshifts into 1st without a problem. I don't really feel the shift from 1st --> 2nd when starting from a stop, and doing 40-50 it's pretty wound up (RPM). If I let off the gas and get back in it the trans doesn't upshift (to 3rd/etc). It just feels like it's always in 2nd gear. Fuses are OK (no blown ones, just a burned out taillight that blew the taillight fuse). I checked the trans fluid when I bought it it was nice & red. I don't know if it has a burnt smell or not, I'll have to drive it and then check. The trans fluid level is within spec as well
4.3l 4x4 '94 S10 blazer 'W' motor
feels like it's not getting out of 2nd gear
speedo, odo, trip odo not functioning
ABS light on
SES light NOT on
no blown fuses
All of this is pointing me towards either the VSS is malfunctioning or the wires to it are not connected/destroyed/something is wrong. Am I barking up the right tree here?

is leading me to think that I am currently in Limp mode, and have some electrical issue with the trans (vss, etc).
I haven't checked underhood fuses yet, but that is on the list. Underhood fuses and the wiring to the VSS. :fingers crossed:
