5-speed for 69 C10?
 
I've searched and read what I can find about 5-speed swap into C10. Most discussions involve swapping a Camaro 5 speed using the Camaro's bellhousing. My 69 307/3-speed bellhousing has mounts to the frame on the bellhousing - the camaro bellhousing wouldn't have that. Is there a 5 speed that can swap in that would use the existing 69 C10 belhousing and clutch fork etc.?

Not sure about the bell housing mounts. I know Brad just installed a T5 to his I6, he might have some insight. Not sure what housing he used.

Wonder what years S10 5-speed? It doesn't look like the 99 S10 5-speed would work based on this picture of one.

Any S-10 with the TBI 4.3 in it would work. '87 or '88 .. whenever they started using the 4.3 .. to '95, probably. But they all had hydraulic clutches.

i wouldnt think that an s10 trans would be that strong or durable when any real power was applied.

But - he's not using the stock bellhousing. My 69 307/3-speed bellhousing has mounts to the frame on the bellhousing and I'd like find a 5 speed that would mount to it - that way I don't have to put in a rear crossmember. Maybe there isn't anything that will work.

Re: 5-speed for 69 C10?
 
:hi2: i belive the camaro 5 speed will bolt up to the stock bellhousing.but the shifter may hit the seat. the s-10 5 speed would require modifacations (drill out mounting holes,trim input shaft,ect..) the trick thing to do is install the s-10 tailshaft onto the camaro trans.that way it puts the stick in the center of the floor. there is a good artical on this in stovebolt and the inlinners.com this is a cheap way to go if you drive like grandpa (the camaro trans is only good to 300hp max) if you can afford it, the tremec tko600 will bolt up and is good to 600hp. just my 2 cents:metal:

The camaro 5 speed is not that stout. They were only installed behind the 305 and were not even offered with the 350. I would find a 5 speed from a early 90's pickup for durabilitly.

I don't know the answer to the OP,but I'd like to point out that a 1969 307 in stock tune,burning the more potent gas of that era was rated at 200 gross hp (150-157 net) and 300 ft/lbs torque (255-260 net depending on smog equipment). That was for a new motor at 9.0-1 compression.
So I would say that's a plan unless you have make substantial performance upgrades.

A Tremec TKO 5 speed would work with your current bellhousing.
I have one in my truck.
I have a 250/6cyl in my 71 shortbed stepside.

I replaced my Saginaw 3-speed with a Tremec TKO 5-speed after the syncros went south in the 3-speed. Bought the Tremec with the mid location shifter from Forte's parts. The middle shift location works great if you have a bench seat and the motor is mounted in the 6cyl location.
http://fortesparts.com

Didn't like the mid location shifter that Forte's provides. The handle lever is just too short and angled back to nearly hit the bench seat.

Found out that Hanlon Motorsports
http://hanlonmotorsports.com
is a dealer for a mid location Pro 5.0 shifter that allows use of a bolt on Hurst shift lever (Hurst lever# 538-6900). I needed to make a spacer to fill the difference from the 6mm bolts that the Pro 5.0 shifter uses and the 3/8 in. bolt holes in the Hurst shift lever. Used brass tubing to make up the difference.

I used my original 1971 bellhousing, flywheel, and clutch linkage. The clutch is a 10.4in. centerforce I for a mid 80's camaro V8 w/ T5 tranny. The throw out bearing is the one for the 71 truck V8 with manual tranny.

I had a local machine shop press fit a spacer to make up the difference in the diameter of the throwout bearing retainer to the diameter of the bellhousing hole in the truck bellhousing (4.685in. vs. 5.124in. on the truck bellhousing). It is really a good idea for long transmission and clutch life to have a spacer ring pressed on to the TKO bearing retainer to make up the difference from 4.683in. to 5.124in. First pic is the spacer pressed onto the throught bearing retainer


I needed to use a high hump tranny cover because the Tremec rested up against the low hump cover when installed.

I used a auto tranny rear crossmember from Early Classic Enterprises to support the rear of the transmission. The TKO has a mounting boss on the tailshaft to accomidate the torque rod for a 3rd gen? Camaro That had to be trimmed to clear the crossmember. Second and third pic is the before and after on the tailshaft.

I had a new shorter driveshaft made by Denny's Driveshafts.

I put a Tremec 5-speed behind my '67 I6 with the mid-position shifter and a auto trans crossmember. I eliminated the crossmember under the bellhousing completely to gain exhaust clearance. Used all new I6 clutch parts and the stock bell with a retro Ansen Aluminum flywheel. I didn't have to make up any other spacers or special parts. It was a total bolt-in.

I couldn't find a chevy truck auto crosmember when I swapped over to the Tremec. here is a picture of the clearance with the ECE crosmember and trimmed tailhousing. Another picture is the shift lever in place.

Nitro Mike, what shifter and shift lever are you using? Your shift lever looks shorter than mine. I like it. It would make the throws a little shorter (not that they are excessive for me now).

Re: 5-speed for 69 C10?
 
X 3 on the Tremec!!! Ours still "hangs" from the factory rear Xmember under the bell housing. We also didn't trim the floor away as you did. Ours was tight but didn't have to trim. We also used the mid-shift location. It is by far the best investment on the truck. We'll see how it does behind the blower now!

Also, if you use the T-5 from the Camaro don't forget that it is canted to one side. And it does bolt right into the bell housing from the I 6. The shifter will end up right under the bench seat as well. I know because I tried this before the Tremec. I wouldn't go that route.

Re: 5-speed for 69 C10?
 
I just put a T-5 behind my I-6. Hmmmm, interesting letter combination-but I digress. Initially I was going to use a 1989 S-10 T-5 but that was going to be much more work, instead I used a 1985 Camaro trans and it's virtually a bolt on deal. There are some things you need to do and I'll do a writeup within a few days.

Re: 5-speed for 69 C10?
 
i'm pretty sure an early 90's fullsize or s-10 have the same transmission i believe it was an nv3550

awesome brad, I'll be looking forward to that writeup! I am planning on doing something similar within the next few months.

1967 was the last year the truck bellhousing had a 4.685in. bellhousing hole.
1968 and up had a larger 5.125in. bellhousing hole. That is why the 67 trucks didn't need the throughout bearing spacer like I did.

It really helps to locate the transmission accurately for long clutch and transmission life. Having said this, There are people who put the small retainer into the large bellhousing and it seems to work. Just something to remember if the clutch gets trashed prematurely.

I did install the Tremec at first with the low hump cab. There was less than 1/2 in. clearence between the top of the transmission and the floorboard. It is not the best picture, but you see it is really tight. Maybe if I had new cab bushings and floor supports there might have been enough clearance. That is why I went to a high hump cover. Easier to service the transmission in the future if necessary.

The New Venture NV3550 (second picture) is not the same transmission as the Tremec 3550,TKO series (third picture) transmission. Different companies.

Re: 5-speed for 69 C10?
 
So where would I get a Tremec for my '69? Does it bolt up to the stock 350 bell housing? I like my granny 4, but a nice 5 would be great!

Huck 01-15-2007 10:11 PM

Re: 5-speed for 69 C10?
 
I put a NV3500 out of a full size 96 chev truck into my 72 cheyenne with a crate 350. It was a direct bolt up from the trans with it's attached bellhousing to the block. Used a stock auto crossmember. Used it's hydrl clutch setup. The 5 speed was GREAT. No issues for several years. Only thing i didn't like is the throwout bearing would self adjust--. That and the fact that the transmission needed electronic hookup for the speedo--no simple way around that!

HotRodWorks.Com has a spacer that allows the swap. hotrodworks.com or by telephone 208.463.1068 (you can view the part @ http://hotrodworks.com/catalog/index...product_id=119) the website could be easier to navigate. It looks like the spacer is for pre-55 Chevy passenger cars. I contacted them directly for clarification; it's designed to fit these trucks. I haven't attempted the swap, hopefully this summer, if it ever stops raining here in Central Indiana. The transmission is about $200 used and the adapter is $160, a new clutch assembly under $150 (I hope).

I want to upgrade my 71 4X4 to a 5 speed manual. have read the nv3500 is extremely difficult to rebuild and has been known to have some problems.

Most of the post I read are from guys much more tech savy than I am, and nearly all are dealing with lowered 2wd trucks. I on the other hand have raised my 4wd and have the added issue of a transfercase. Anyone working on a 4wd?

Re: 5-speed for 69 C10?
 
To clear up a few things the early 4 and 2.8 6's had the T-5 the mid year 88 model year[was a half year change] when the 4.3 was first made available in the S-10, and the 4.3 was the only one to get the NV3500. the others had the T-5's. The best way to do this the way I have researched it and plan on doing it for my "project Cheapie"are to use a V-8 T-5 trans from a Camaro and a tail housing from a S-10 to move the shifter into a better location in the cab. I know that is taking two to make one but I scrounged around and ended up with both for only $150 so I think it is still doable and since it will bolt to the bellhousing where the three speed was is the best route to go.
