was wondering if any forum members ever come across a good used
tremec 5 speed for sale?

i have been searching ebay and craigslist for almost a year now and i
not seen any tremec 5 speeds for sale. i have seen a few keisler for
sale but i dont think i want a keisler since they are out of business and
u cant get parts for them.

i have been wanting to replace my muncie 4 speed with a 5 speed but
i really dont want to pay $4K for a new Tremec TKO 600.

any ideas where i can get a used Tremec 5 speed? i guess when some
people put in a 5 speed they like it so much they never take it out??

i will keep searching maybe someday soon i will get lucky and find one?

any other suggestions are appreciated.

Sure..., Tranzilla takes a 600 TKO, goes through it, modifies it to make it shift nice up to 8K RPM, and sells it for $3K.

They'll do the mods on someone's TKO600 for $2K.

They're only $2600 new available everywhere. As far as used transmission go, IMO there's only two types, those that have just been rebuilt and those that need rebuilt. I would never install a used trans. without tearing it apart and at least checking it out.

You do realize a standard run-of-the-mill Tremec 5-speed, especially any one you might find at a auto salvage yard or online will have the shifter center mounted on the tail shaft, and it WILL NOT fit up thru the shifter hole in your C2. In order to make these work for us in C2 cars, the shifter has to be side-mounted and offset towards the driver about 3" or so in order to be centered in the console hole. Thats why a lot of peeps, myself included opt for the kit from various businesses that make these modifications. Also a Tremec 600 5-speed is about 3" or so longer in length than a Muncie ... so you will need a shorter driveshaft. That's why the new tranny kits for C2's are so much more than an off-the-shelf TKO 600/ Fyi, Bill

Keisler is basically a Tremec, right? IIRC they just modified the shifter, mount and location. Case and internals the same. Now taken over and sold by Silver Sport?

Frankie the Fink

Pretty much...

The Keisler 'value added' was their kit. Everything came with it if you went that far, right down to the 5 speed shifter console plate. I installed it in the '61 and after many thousands of miles it developed an occasional grind when upshifting quickly. Annoying and inexplicable since the units were spec'ed for far more horsepower than my 283 could ever develop.

To wit, yes, if you are buying a used transmission, have it checked out before installation. There are also some outfits that modify the internals so the often-complained-about 2-3 shift is smoother...

SST CNC machines the stock Tremec case for their shifter. The tranny is then reassembled, put on their test spin fixture (electric motor input), and run thru the gears. The transmission is pressurized in this fixture to some small pressure to verify there's no leaks. What leaves SST is not a stock tremec. I toured their shop when I picked up my 600 kit. You may save a grand or so but you'll have to engineer the rear mount and probably how the shifter matches the stock hole. In the end you'll probably wish you had just bought the kit. I'd absolutely use SST again.

toddalin

Agreed, and I have a Keisler TKO-600. Not only did they include the stuff mentioned, but also the new driveshaft and clutch plate.

Also, you called Keisler and told them what rear end you had and what size your tires were, and they would install the appropriate speedo gear before sending it out.

sorry 1snake but a new tremec 5 speed for a c2 corvette is $4K.

only ones i have seen for $2400 new is for a mustang or camaro?

not a c2 corvette as the shifter is in a different position and the
machining is a lot different for a c2 corvette. if i could find one for
my c2 corvette new for $2400 i would buy it right now, but they are
$4k for a new one. but thanks for your input,

toddalin

Tranzilla fixes this problem by installing a different "engagement" piece that has a blunt, rather than a tapered end. The taper would let this piece slide between the its engagement points on this upshift.

You didn't specify that you were looking for an aftermarket modified one or a conversion kit.

tuxnharley

My point to the OP - which I guess I didn't express very well - is that if you are looking for a used transmission there is no reason to shy away from a Keisler vs a Tremec, as the Keisler IS a Tremec, just with mounts and shifter designed to fit in a C2.

Internal parts are the same and are available.

As for the 2-3 shift, I have never had a problem with mine. Yes, it is different than a Muncie as the shift pattern is different, being a 5 spd vs the Muncie 4 spd. With the Muncie you can slam it from 2-3 as it is up against the stops and there is no place else for the shift to wind up. With the Tremec/Keisler it is a spring loaded centering shifter that will go to 3rd if you just guide it and let it center. If you try to slam it it will either hang up on the 2-3 gate or wind up in 5th.

Perhaps a heavy handed approach is why some have had 2-3 problems?

If you want to drag race/power shift etc the Muncie is a better choice. If you interest is in street/highway driving with a choice of gear ratios and an overdrive 5th, go with the Tremec/Keisler.

I have 7 -8 years and 10,000 plus miles on mine now with no problems.

I'm in the 'buy the right one for the car and buy it new' camp. Pretty much anybody who's driven a 5 speed in a former 4 speed car is not going back to a 4 speed. And any used transmission is suspect and needs teardown and inspection. 5 speed conversions are expensive and will not pay for themselves in fuel savings unless you drive another 300,000 miles. The reason most install them is to simply make the car much more enjoyable to drive. We have been spoiled by overdrive transmissions in newer cars over the past 30 years, and driving all day long at 3500 rpm is something most of us have 'outgrown'.

Dr L-88

Well stated and I'm from the same camp.

BK N 66

thanks GTO guy

and i agree with u 100%. i am just looking to replace my 4 muncie with a 5 speed
tremec with overdrive as most of my driving is on the freeway.

so i will look at the tremec as mentioned above for 3K. which i could probably swing,

if i have to pay 4K for one i think i will pass and just leave my muncie 4 speed in the car
as i dont drive the car that much except in the spring and summer.

thanks for all your help and imput. sounds like i should just wait and get a new 5 speed
and forget about a used one. thanks again

Silver Sport Transmission is also another source. I did not call and find out how much it costs.

Yup. See post #5

I recently purchased C2 with a 5 speed, with less than 400 miles on it. Installed by a shop in PA. I can send you pictures as I am returning my car back to the way it was born and I will be selling all of this drive train, Transmission, Rear tranny mount ,Drive-shaft, floor pan pads, speedo drive and cable, as well as Center Force Clutch. It would be ready to install in your C2 and you would not need to buy anything else. Not sure about shipping and not sure where you are located. Here is a pic that I had in my phone, not the best but I will get more pics in the AM when I get to my shop. I do have all of the paperwork for the transmission kit as well from the previous owner.

Now I know they don't match up to the other transmission's mentioned above..... but have you considered a rebuilt Chevy World Class T5?

Put one in my 68, loved it so much I converted my 77.

Going on 11 years, BB 400 hp. Zero issues.

Good luck, you will love it.

Here is the kit that I have. It was installed in 2007 and it is a TKO-500. The system has less than 400 miles on it, this information, from the previous owner. As I stated previously, I am putting the car back tot he way it was born so these very nice items are going to be replaced. I am asking $2950.00 for the Transmission, shifter kit for the C2, Speed o drive unit and cable, drive shaft, rear transmission mount as well as a center force clutch.
