Doorgunner's '68 Convertible Project





My next trip will be to machine the other end to mate with the 4L60 mechanical speedo-housing....drill/tap bolt holes....machine flats on the adapter.

I made a quick trip to the garage to disassemble the drums in the 4L60E transmission/I'm still trying to learn the terminology for the individual pieces.
I had to fabricate a $120 spring compressor to disassemble the drums/
REVERSE somethin'/somethin'.......
MAIN SERVO somethin'......
FORWARD somethin'/somethin'
I will order a Seal/O-ring Overhaul Kit this week and reassemble the Reverse Drum and output shaft.
Then I will be able to verify the thickness of the adapter I am machining for the new tailshaft housing to make sure the speedometer Drive gear and the Driven gear mesh.
Meanwhile I still need to install the weatherstrip pieces for the deck lid......

I just updated the last FORTY pages of "The Table of Contents" in my thread........
just in case anyone needs to know HOW NOT TO DO SOMETHING!

9/10/2013.................
NOTE: When I started this thread, I had no idea of what life had in store...so this is turning into more than a build-thread.
I'm new to Corvettes and want to buy a very neglected '68 convertible near my home with late '70s front & rear bumpers....
Side note: I've had the "fever" since 1968 when I saw that $4,550 red Corvette on the showroom floor at the local dealership.....and ended up with the $2,695 1969 Camaro convertible that was sitting next to the Corvette!
I'm not trying to "restore" to a factoy look since the car is a "basket-case" vehicle......I have no bodywork experience.....just want to get the body back to 1968-looks....and have a D.D./keeper just for me.....
Thanks for any input/threads-to-read...since I'm learning as I go....
Some of the experimental mods that I try on this car would NEVER EVER be tried by me on an original car!

Well....I have a choice between a $500 transmission controller......and a $60 gizmo that I have to learn how to write a program for. I'd rather do TWO rebuilds that write a program ("Old Dog/New Tricks"
)So...what Ima gonna do is do dry rebuilds on the trans using the original parts until I get the time down to One/1 hour

Annnnd I'll villeo it to prove it happened
