I have used TH400s since 1987. First one was in a '72 Buick. I ran that car for 16 years. My next car was and is still is a '71 Buick which is my primary tow vehicle. I cooked than tranny several times. Once on a long steep pull. 3/4 of the way up that climb I noticed a lot a white smoke billowing from the rear of the car. There was no pull off space until I crested the hill. I allowed some cool down time then continued our travels. When I got home I drained the tranny, changed the filter and noticed some metal in the tranny pan. Towed with that tranny for another 4 years. When I had the engine rebuilt I thought best to have that tranny gone through too. The tranny mechanic said he so no real wear. I had smoked that tranny another time too. I am towing with than tranny today PLUS with the 400 that's in my '69 Olds TV. My '75 Jeep 3/4 ton pickup has a 400 behind a Buick 455.
I am sure the new computer driven trans are better but for this old and 'old school' guy with his old vehicles with the old TH400s I am a fan.
