I've repaired two transmissions in my life. One was a Turbo 350 in a 71
Caprice. I tore it completely apart, and was prepared to tank all the
parts I was reusing. I had them in a crate behind the parts washer at
our hardware store. Somebody decided to use the parts washer, and
dumped the brick on top (to keep it from blowing open) into my box of
parts by lifting the lid instead of setting it aside. It broke a
(piston?) large ring with a seal and springs mounted on it. I was broke
after buying the rebuild kit so I was stuck. I think my dad broke it
because he scrapped another transmission to get me a replacement piston
out of another 350. It was the same dimensions, but had fewer springs
on it. I put it all together and it worked great for a couple months,
and then progressively started to fail. It got worse and worse. I left
the car behind on a fairgrounds in Redlands California because it
wouldn't move. The other was a manual transmission in a Ford F150. I
didn't even take the transmission out. I just ripped out the floor
liner, pulled the floor cover, pulled the top of the transmission out,
and snapped on new nylon shifting fork riders. Worked perfectly.
In the past I wrenched because I had to. Now I wrench because I hate
paying somebody to not quite do it right. I can not quite do it right
myself and make my own decision about whether or not its good enough
instead of being surprised when I have to walk home.
I'm a big fan of RV cams (long duration) in "trucks." I put one in a
1982 Bronco with a 351. It would slow walk at idle in first almost as
slow as an old 4 banger Jeep and climb a steep grade doing it. The
other was a 76 Ford F150 (yeah the one above) with a bored over 360. It
would slow walk (crawl) ok, but the big thing is it would tow almost
anything. Not much top end, but if you kept it in its power band when
you shifted it would get to top end in a hurry. That truck had so much
torque I had to drill and bolt through the motor mounts because they
kept tearing when the engine lifted up.
