Having problems with your 1986 GMC Suburban ?
No movement in any gears
\015 I just purchased a 86 suburban with a rebuilt 350 700r4 overdrive auto trans 2 wheel drive my problem is the previous owner was driving along and suddenly it was like it went in to neutral. Theres no movement throughout the whole range of gears (r,1,2,d,od). And rpm and engine noise don't change \015\012while shifting.\015\012 any ideas?\015
Thats a real simple unit, either the pumps input shaft sheared or the drive hub that that shaft engages into the torq converters spot welds broke. happens on rebuilt torq converters from time to time, either way its gota get pulled. a 2wd is very easy to remove and cheap to repair good luck!
