Well my car has 99,000 , the person before me i'm sure didn't service the trans. The fluid was a light brown...looked like clean motor oil, not burnt or black or anything.

Once it warms up, It slips from first gear, and it will start to make a howling noise. Only when warm though. Once past 20 mph it rides fine. from reading around I'm sure its the trans pump.

I changed the filter and fluid with the new vi fluid and maybe made the howling noise louder. It defiantly didn't make he shifting better or worse.

What should my next step be , I hope to get as many miles out the trans as possible.

Should I drop pan and change filter and fluid again an add bottle Lucas..... Or just add it to the fluid I have in there now.

Should I go back to the older fluid?
