Need help diagnosing tranny issue

Looks like my transmission is goin out...Its started slipping in second gear really bad and now i discovered today that first gear is slipping now...when i drive off the revs and then then tranny catches itself and goes. I changed the filter in the summer and put fresh fluid. When it first started slipping i topped off the fluid but it still slips...so what can it be...are the clutches burnt out or is it something else?

Re: Need help diagnosing tranny issue

Was the fluid checked while hot, engine running, trans in park? Proper dipstick and tube and not a Chinese chrome set ?

Re: Need help diagnosing tranny issue

You can put a 350 behind a 5.3 lol.

It sounds like the converter is bad.
