So I think my TH350 is FUBAR

[rough69]

Well I think it is time for me to face the facts and pull the trans tomorrow. What do y'all think?

When I got the truck running it made a really high pitched whine like a gear drive was installed on the truck, but I figured it was the water pump / alternator as both accesories were old and sat around for a while.

Well I replaced both (the WP bearing was pretty bad), got the truck running well and even fixed the brakes (sweet!).

But the whine is still there but now it seems to go away after the truck warms up a bit and the truck has always had a whine when it is shut off that sounds like a jet engine slowing down (errrrrrrr stop).

Now that I can actually drive this thing, I noticed that it does go into all gears, but Reverse takes a few seconds to engage sometimes AND upon acceleration makes the truck shudder real bad.

Also, I know for a fact that the truck, when engaged in reverse, is NOT supposed to roll forward and it rolled a bit down my driveway (which is steep) while in reverse until I gave it some gas.

AND Freeway speeds seem impossible!

I mean I don't know what gears are in this truck (they feel like 4.11's?) or where to look for a ratio, but it seems like the truck won't do over 50MPH in third, but the motor sounds like it is doing ~3000RPM+ and going 100MPH.

Truck is a '69 C10 SWB 350, short shaft TH350, just had the driveshaft fully rebuilt with spicer universals and a new carrier bearing.
