took the 90 in to transmission shop and was quoted 1200$$$ to 1800 $$$ for a rebuild , is that about normal??when cold it takes alot to change to 2nd or 3rd and will not go to overdrive but when warmed up , shifts perfect with the exception of no overdrive. and was told rebuild or replace was my options. just wanted someone to say yeah man that sounds right or should i get another shops opinion? t v cable is fine...
