Overdrive Issues

[marcelus77]

Hi there everyone i really do hope someone out there can help me as i seem to be having problems with my 1993 mk4 toyota supra 3.0 auto , it has developed this sort of lurching motion when the overdrive is on and also stalls out when at a stand still and wont start again untill you switch the overdrive off . With the overdrive off it works fine apart from using more fuel than usual , just wondered if anyone else has had this problem and if so what is it most likely to be

many thanks
