hey,
it just started to do this a couple weeks ago, all of a sudden it shifted from o.d. to drive on the freeway. it kept shifting back and forth on it's own so now i manually have turned of the overdrive and everything is fine, besides the 3000+ r.p.m. if i have to do 60-65mph. every once in a while i'll push the button to engage the o.d. and it will shift up but only for a short period of time. and when it does kick up into o.d. sometimes it stays for a mile or 2 and other times it will kick in and out a couple times before just staying in third. tranny doesn't slip and still shifts good even in and out of o.d.

any suggestions, or a place to start checking?any and all info. will be greatly appreciated.

thank you, Jon

Jon,

Not to be rude or anything, but could you please post your question in the appropriate forum? There is not, nor has the ever been, a Toyota "muscle car".
