Replacing 3.03 tranny gaskets

Post #1 by StarDiero75 » Sun Dec 10, 2017 6:14 pm

Howdy guys,

So i got a 65 200 Ranchero and someone in the past ditched the 2.77 for the 3.03, thank god. But now it leaks. Im looking at replacing the gaskets, is this a huge job? It looks perty simple in the diagrams from my shop manual but its a Ford so it cant be, hehehe.

Also, if i do have to tear it up trying to replace the gaskets, how hard at the point would it be to rebuild it, like new synchros and crap? I saw a rebuild kit for $120 or something. It pops out of 2nd which is why im considering it.

Let me know,
Ryan

Im replacing the clutch which is why im even considering doing any of this. These are 10" or 9 1/4" right?

Hi, I am not a tranny expert but I have worked on some. The gaskets can be replaced with silicone, but you must find the correct seals.
I would leave the popping out of second to an expert.
Good luck
B RON CO. Still workin' on it!

I have found the right gasket kit, rockauto has that.
Yeah i was thinking the same but i cant afford that. Thats why im considering doing it myself. But if i goof its a big deal. Ill ask around and see what people say. What do you think itd cost to have a pro do it?
