Drop the trans, or the whole thing. Options

[TheCabinetmaker]

I've had either a rear crank seal or a trans input shaft seal, or both, leaking for some time now. Clutch has been slipping slightly, and I've been babying it. Yesterday the clutch gave it up. I also need to replace pushrod tube seals and motor mounts. I'm presently building a 2056 with Raby 9550 cam, so I'll be swapping engines in the near future. The swap will be a complete long block, tin and all. Pull engine, install trans, and install new engine. Now to my dilemma.
Should I,
1. pull the trans and replace seals and clutch only and drive?
2. pull engine and trans, replace seals, clutch, and pushrod tube seals
3. Pull it all and wait for the new motor and drive the truck?

IMHO plan to pull all (2) - it's easy full drivetrain drop as you probably know & plan to do a 2-fer, but assess what else might be going on with the engine while you've got it out that may need to be taken care of, then decide if it's a 2.5 (out for a bit to take care of more stuff) or full on 3 (too much to f-with & may as well spend the time on the 2056). Plus you can probably use that time to get in the new motor & transaxle mounts, etc. in advance of the 2056, for a faster engine swap later.

As you know, if you plan on 3 from the git go, shit happens in life & time can stretch out on it. So if you can get it out & back in & running well, then you'll have a solid 25-30 mpg driver back there where the distances to stuff can be far (& on fun roads), as well as checking out whether you then have a solid back-up engine if the 2056 has quirks to resolve &/or if you want to sell the "extra" old small displ. motor.

BTW - glad you got the newbie on here from Tulsa hooked up with the 914 group there, & helped him with his headlight issues.
