My transmission loses all torque after driving for a little bit (around the parking lot). I dont trust it enough to take it on the road. Its a 90 Integra GS with a B18a engine and transmission (stock). I just put in a junk yard transmission 7 months ago and cant determine if the torque converter is failing or if I need a friction modifier. It ran great after the transmission swap and now before it warms up it has full torque and shifts just fine. I also need any links to a site with rebuilt or semi-performance torque converters I could not find any online or at parts stores.
