My brother sold his '91 Celica GT to his girl with 100k+ on the clock. It is a GT coupe with 5 speed manual. He says about a month ago it started leaking the Dextron III ATF that he had been religious about changing every 15k or so. Seems to be leaking around the P/S pump area. He put Bars a leak P/S and auto tranny stop a leak in it and it slowed it but did not fix it. Is this likely a hose fiting or hose failure of a pump problem?
