Im having trouble searching this forum, so dont get mad if another thread already exists about this issue....
I recently changed my fluid and filter on my TH400 transmission from my 78 k20 4x4. It ran fine before, just had a leaky gasket. After the fluid change, now the truck wont go anywhere. It shifts into all gears, but when it is in any drive gear it makes a spinning noise ( like something isnt engaging maybe ). The noise didnt sound good, so i turned off the engine and havnt turned it on again.
Does anyone have any clue what might have happened?
let me know thanks
