Default 4 speed swap almost...

First to the guys that have done the swap, i give you alot of respect, some things were a complete bit(ch.



I do have a few questions though, i took it for its first test drive, i was real easy on it knowing that it needs some break in time.
i had a small smell of clutch after about 5-7 miles driving. I didnt smell it until pulling in the driveway though.

Second questions i have a small faint squeal noise only when clutch is engaging (clutch pedal coming up) and only when in gear. It did get more faint from leaving driveway to coming back after the 5-7 mile drive.

Third i cant get the speedo cable hold down on trans to fit, cable goes in and speedo works, im sure they are different for auto and manual, part number?
Any help guys thanks

2. 621 bellhousing $125(swap meet)
3. pedal assembly and linkage to clutch for $175 shipped(from here)
4. flywheel 456N $10(back of blazer in junk yard) ($35 to resurface)
5. clutch fork $70 (ebay)
6. lower shift boot $25(ebay)
7. clutch 11inch $135 (NAPA) NAME BRAND LUK
8. hurst shifter 20$ swap meet ( clean and put back together 1 hr labor

Default clutch

sounds like (smells like) the linkage is binding up or the pedal not returning all the way letting the clutch slip.

it is a tough job to this conversion-woth it when done.

I don't know...seems like an awful lot of trouble, not to mention expense, to do the shifting for yourself.

Hi l-w77,
4 Speed.... VERY nice! Well worth the effort.
I looked in my 71 AIM and the speedo cable retainer at the transmission is # 3708148. There's also a seal shown, #3708146.
I don't know if that will help on your 69 muncie. Maybe?
I'm sorry I'm not enough of a mechanic to help with the rest of your questions.
Good Luck!
Regards,
Alan

It may have been pedal linkage, but no more smell now. Just need to mold sheet metal for hole and install lower shift boot and the swap will be done .

I do too! But an overwhelming amount of C3 forum members genuflect at the alter of an auto trans, they can't all be wrong. Can they?

Alan 71 thanks, thats exactly what im looking for.

69 Chevy, didnt mean any disrespect, i looked and looked for a 4 speed when i bought mine but it seemed like they had dried up so i bought a auto car and saved for 3 years to be able to get all the parts (military doesnt pay all that well) for the 4 speed swap, i did look into the 5 speed W/C trans but they wanted a small fortune it seemed, i live on a island and the top speed as per speed limit is 55 mph.

I know now how to do the swap and where short cuts can and cant be taken, hopefully i can help people in the future on here.

I'm partial to the 4 speed, too. I can't imagine having an automatic in a Vette. I guess it comes from the generation I'm from. Back in the day, the ones driven by guys were 4 speeds and the ones driven by someone's mom were autos. My DD is an auto, but for fun, nothing beats shifting!

I did a 4 speed swap and when I pushed in the pedal down I got a squeel too. I found the problem. I had the clutch fork in the wrong slot in the throw out bearing. Fixed it and it works fine.

Well a update guys car is great, smell was rear brakes I overtightened the emergency brake cable and they were dragging, ceramic pads smell a lot like a clutch, noise is gone too. If only the corvette shops around the world knew there were corvette experts on this site, they might get on here just for help.
