700r4 need some advice from fellow third gen members
91 RS 305 TBI 700r4 3.23 rearend.....
Bought the car about 2 months ago after it has been sitting for over 10years. i changed fluids and spark plugs and etc,... car started up and engine ran great. next was the transmission which i was not looking forward to at all. just for sh*ts and giggles i decided to take it for a drive, it shifted godd under low throttle. but during hard acceleration it acted like something was holding it back from shifting from 2nd to 3rd and 3rd to 4th(OD). i changed the transmisson filter and the fluid was about as black as oil. added new fluid and wrmed the car up for about 30mins per the service manual to check the fluid, all looed good. took it for another drive shifted great under low throttle, shifted decent enough in mild throttle, kinda rough though, and same issue as before under hard throttle acts like something is holding it back from shifting, once i let off the throttle alittle it shifts right into 3rd then shifts normal into OD. i have checked the TV cable and it is where is should be as well.
so, before the new filter an fluid hardly anyshifting in mild throttle, after filter and new fluid shifts in mild but not in WOT.
could it be something stuck not allowing to to shift at proper line pressure under WOT, or is the transmission clutch packs taking a dump from 2-3?

Well if the fluid was really black, and smelled burnt chances are it needs a rebuild. You have no 2nd gear right? Is the T.V cable hooked up and adjusted correctly?
