Default Tremec 600

Local guy is selling his used tremec 600 5 speed final gear is .64. Asking price is 2000. Is this a good price? Also what other parts will I need if I decided to buy it (I.e. flywheel, bell housing, drive shaft etc)? I can t tell but from outside it looks pretty new. Inside, I have no idea.

FYI, it s out of a 69 camaro.

If it has been used out of warranty, $2000.00 seems high to me. Brand new units can be purchased from Summit for $2295.00. If you are swapping from automatic you will need offset shifter, bell housing, clutch and pressure plate kit, clutch fork and all linkage, pedals, trans mount and adapter, and a modified driveshaft. New Speedo cable, assorted wiring for your reverse lights and neutral safety circuits. If you want it to look right, you will need new or fab the shifter console.

btw...it's well worth the effort.! Totally different car!

Thanks for the info. It will be replacing m21. I didn't see a tremec 600 for 2300 at summit. I m going to check it out. I ll buy a new one for that price. Do I need to replace those mentioned parts if I currently have a m21. I have a 4.11 rears and it s wearing me out these days.

If you're swapping from M-21 you can re-use all your clutch linkage, pedals and bell housing I believe. If your cross member is welded in, it makes the install a little more troublesome there, but you save all kinds of frustration not having to swap the pedals. the driveshaft mod is still required as are the trans mount mods. You will also need the offset shifter. Search on some old threads some guys have made simple U brackets to achieve the required shifter location and saved some $$$.

Kiesler sells the TKO 600 with an offset shifter just for C3's, dont know the price, they have a complete kit called Perfect Fit, works like a champ and has every part, driveshaft, yoke, etc except shifter handle for about 3500 I think, may have gone up since my purchase.
Thanks, Keith

You need more than an offset shifter to fit a TKO in a C3 without modifying the tunnel.
The C3 specific units cost more that the standard 'out of the box' TKOs because they need to machine the tail shaft in order to get the offset shifter to come out in the proper location on a C3.

With all the possible mod involved, I may as well pay more and buy kissler perfect fit tremec 600 instead.

Not sure-
You can always contact a TKO retailer like Keisler or American Powertrain etc to see if they would be willing to machine your existing tailshaft for you.
My guess though is that at the end of the day, you'll end up spending as much modifying a non-C3 box than just getting the proper one to begin with.

Or you can do something like this:





It's really not that hard to do.

I purchase an the Mcleod Slik Stik. For TKO 500 & 600.
Nice piece with offsets to suit specific applications.
You can order it with or without stops.
http://www.mcleodracing.com/products...00+%26+600.mcl

I purchase the crossmember mount and driveshaft from Keisler, The mount fit well but the driveshaft was too long so I had to have it shortened and rebalanced locally.
Keisler told me that my something in my chassis / Drivetrain is not the standard measurement
Thats possible because nothing is original.
Confirm the measurement instead of just ordering by application.

I don't mean to be the bear of bad news but the TKO 600 will be better that the M21 with 4:11 gears but you still won't like it. Keep in mind that the TKO has a lower first gear, and with 4:11 gears you will never use 1st gear again so basicly you will be using a 4 speed again. And it gets worse than that because in any trans the strongest gear is first gear and the weakest is top gear. The TKO is a bit stronger than the M21 to start with, so it will end up about the same in the long run. Most all modern OD trans are intended for 3:0 to 3:5 Gear ratios, and untill You go there I don' t think You will be happy. Since there is always somebody out there who wants a performace 4:11 ratio, selling or swaping shouldn't be that hard to do.

What did they charge you for the mount and the driveshaft?

Thanks. I'm also trying to determin if it is worth doing the conversion with a used "standard" Tremec vs a modified Keisler.

Nice work- This looks like an auto to stick conversion?
Looks like you have a pretty good sized hole in the tunnel based on the size of the sheet metal plate you have there-

On a 4-speed car, you'd have to cut another hole in the tunnel to make this arrangement work.
Doable but you have to be willing to do the surgery.

I have had a TKO is my 65 for several years. With 370's first gear is a little low. While I like the OD, I am disappointed as to how difficult it is to shift. Forget about the speed shifts done with the old Muncie. Additionally the trans is very noisey, especially at idle.

Just put a new TKO 600 in my 73 and I am not having any of those issue. The 2.84 first gear with the 3.70 is great for launch but not "granny" low. The .64 OD is perfect! Completley happy with mine. That said, the tremec is a top loader, so yes it is "diffferent". If you wnat the muncie feel then go with a Richmond!

I"ve had the old 3550 tremec that I put about 15 years ago.
With a 383 and 3:55 gear and a 26" tire it was a very good set up with
the 3:27 1st gear. Well years later I built a 434 with about 575hp and that old 3550 gave up 3rd gear in about a month. Drove the car for like 5 years with no 3rd gear,finally it gave out altogether. That being said the 3:27 1st was rather useless with the 434 motor. I just scored a new in the box never installed TKO 600 the guy bought about a year ago, he wanted to go to 6 speed so he could get a .50 over drive. Anyway I'm looking forward to see how the 2.88 1st gear is with my combo. I haven't driven the car in two years since the other tremec gave up.

I don't use a offset shifter,what I did was switch the boot and the 4 speed data plate. So I have a direct bolt on shift handle I could speed shift with no problems. The only down side to this was I had to remove the ashtray door. I tried the off set shifter and found it wasn't a direct feel for me and it shifter would hit the console.

Just some options to consider.

Found on e-bay from Jegs a new TKO600 shipped is $2365.00
