Howdy all!
I have an 85 454/th400 suburban and my first travel trailer pull (6miles in) caused me to puke out new tranny fluid out the vent tubes. The fluid came out burnt and black so I’m guessing the clutches are shot. Should I rebuild this thing (much cheaper?) or swap to a 4l80e (new shaft, controller, etc?)?
The turbo 400 looked good on the inside but I wonder if being 40 years old made it take the cake when I towed with it?
