Does anyone have any idea what this may be? It doesnt seem mechanical. When i approach speeds over 55, the o/d light willl blink and the truck wont shift into 4th or 5th gear.
yes, your trans is failing.
time for a rebuild or replace.
if it was me, Id go for a replace as it is almost always cheaper than a rebuild. I just replaced the trans in my mothers protege, $300.0 at an auto salvage yard and $250.0 for the mechanic. took him less than a full day.
versus $1200.0 (lowest price quoted) to rebuild it ($1900 was highest)
Im now sure how mechanically inclined you are, but her car is FWD, which is why I wouldnt do it myself, but RWD/4x4 is much easier than FWD
basically with rwd/4x4 the 2 hardest parts of the job are dropping the driveshaft and re-aligning the trans when installing the new one. you dont even need a ton of tools, but it is a good idea to have the use of 2 hyrdolic jacks to make it easy to drop the trans.
