Administrators RTz Posted June 7, 2013 Administrators Share Posted June 7, 2013 The OP doesn’t want to spend the money on an appropriately rated transmission. The TKO600 is rated for about 25% more torque capacity than a T56 and it’s less expensive. But, he won’t break either one unless he gets traction. If he knowingly installs an underrated trans and then proceeds to make modifications to get bite, and consequently breaks the trans, then I’d say the joke is on him.

texis30O Posted June 7, 2013 Author Share Posted June 7, 2013 I have been called worse. all jokes aside I did put a deposit on a built t56 this am. I will first have to get used to the car so I think that this transmission will last a while during the OGM what did I just build phase..... as I get out of that phase and into the OK let's see what it will do phase I will start to look at other options. I bought a built T56 with: LS7 clutch Tick Master Master Cylinder B&M ripper Shifter Steel 3/4 fork Carbon blocker rings on all forward gears Upgraded second gear Billet 3/4 syncro solid 1/2 keys Bronze fork pads 1-6 Modified reverse syncro All new needle bearings I will most likely have to upgrade the clutch but this is a good start for 1800.00 Quote Link to comment Share on other sites More sharing options...

(assuming its for an F Body). Yeah, that LS7 clutch will drive nice, but it won't last long if you beat on it. I'd look at a brass shifter cup bushing as well. I had a B&M in one car - not a huge fan. I have a factory hurst with a short shifter on it. I'd like an MGW ultimately i think. Looks like a good list of parts..... assuming its put together correctly. The dildo who put my current trans together (before i bought and rebuilt it) forgot the shift fork pads, and it ended up grenading the 3/4 synchro hub, and took the counter shaft with it. esssssssppeeeeeeeennnsive.

texis30O Posted June 7, 2013 Author Share Posted June 7, 2013 I thought I got it for a steal. I don't want to have to pull the transmission any time soon so I might just go ahead and get rid of the clutch.......I am new to the LS world so it is good to hear that I have a decent set of parts in the pieces I am putting into the car. I had a budget but.... it has been blown....If I would not have bought the magnacharger I would not be so bad off...... Quote Link to comment Share on other sites More sharing options...
Dans toy Posted June 7, 2013 Share Posted June 7, 2013 Which magnacharger did you buy? new or used ? and what cam are you running ? if you don't mind sharing. Quote Link to comment Share on other sites More sharing options...
EastTnZ Posted June 8, 2013 Share Posted June 8, 2013 A little late to the party but I'm putting a TR6060 in mine. Bone stock of course (more tq capacity drew me towards it) but I couldn't find a T56 for a good deal so we'll see how it goes. Worst case it breaks and I go the built T56 route. Not so happy about the fixed yoke rear but we'll see what happens. Later plans include another car (or old 50's chevy truck) with LS power/Turbo or Supercharger/Auto for a daily driving drag car/truck. Or maybe a duramax powered 50's drag truck! Ok now I'm just rambling... My trans is an '11 with 2k on it from a Camaro SS pullout. $1450 Can't wait for the build on this one! They're all different and I like incorporating different ideas/parts/pieces from other builds...if enough people keep putting on superchargers I may have to eat bologna and cheese sandwiches to save $$ and buy one soon after mine's running! Peer pressure... Quote Link to comment Share on other sites More sharing options...
socorob Posted June 8, 2013 Share Posted June 8, 2013 So given the choice thee seems to be 2 common gear ratio setups on the T56. One has a taller first gear but with lower overdrive .63 i think. I guess a closer ratio trans and the other has a lower first with a higher overdrive .50 I think. What is the preferred one for a swap with a 3.54 rear? Are the gear ratios in te 6060 similar to the t56? Quote Link to comment Share on other sites More sharing options...
EastTnZ Posted June 8, 2013 Share Posted June 8, 2013 Yeah from what I gather, here are the ratios I've dug up for t56 vs tr6060 LS1 T56 - 2.66 , 1.78 , 1.3 , 1.0 , 0.74 , 0.50 TR6060 - 3.01 , 2.07 , 1.43 , 1.0 , 0.84 , 0.57 Camaro TR6060 and T56 not GTO gear ratios Quote Link to comment Share on other sites More sharing options...
texis30O Posted June 10, 2013 Author Share Posted June 10, 2013 The cam is a custom grind Billet unit. I will get the specs on the cam in a bit. I just dropped off the transmission off at the shop where all of my parts are currently at. Call me what you will but I know when I am in over my head. With this build, well I am. I can do the simple swap stuff but this full swap into my 1970 240Z I feel would be best done by the professionals. not a bro-fessional like my self in this arena. I will be updating my build thread as there is progress in the coming months Thank you for all of the responses and information. Quote Link to comment Share on other sites More sharing options...

The M12 gears were used in the boats. aka GTO's and SSR's. Quote Link to comment Share on other sites More sharing options...
EastTnZ Posted July 22, 2013 Share Posted July 22, 2013 (edited) So what are people's thoughts on gear ratios for autoxing vs drag racing vs daily driving? How usable is 1st gear in a T56? I'm close to firing my 5.3 up and am curious with my 3.01 vs 2.66 if first is even usable in my case unless I had a hitch and hauled a trailer lol jk Oh and I have the standard 3.54:1 rear R200 Edited July 22, 2013 by EastTnZ Quote Link to comment Share on other sites More sharing options...
Naptown Dave Posted July 22, 2013 Share Posted July 22, 2013 http://www.f-body.org/gears/ Here is a link to a gear ratio to speed calculator that factors in tire size and final drive ratio.

RebekahsZ Posted July 22, 2013 Share Posted July 22, 2013 I have the GTO tranny. I think you are best off with a 2.66 and a 3.54. The power to weight is so good there is no reason to gear low. You will be out of first in the blink of an eye-second gear even faster. You do need first gear. Quote Link to comment Share on other sites More sharing options...
socorob Posted July 22, 2013 Share Posted July 22, 2013 I was just looking into this since I just ordered a GTO LS1 and T56. This site has tons of info. http://www.eecis.udel.edu/~davis/z28/2010/100201_LS7T56/800-1000hp_rated_LS_Fbody_T56.pdf Quote Link to comment Share on other sites More sharing options...

Phantom Posted July 31, 2013 Share Posted July 31, 2013 Zfan1 - got to agree with you if the car is going to have a solid rear axle. That says straight line car and nothing beats a good auto for that. Since I'm now in the Pacific Northwest and have all these wonderful crooked mountain roads i'm so glad I stuck to my guns 10 years ago and went with the T56. It is so fun selecting the right gear and then throttle steering through the corners. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted August 1, 2013 Share Posted August 1, 2013 Agree 100 percent, a six speed for the twisties is the only way to go! Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted August 1, 2013 Share Posted August 1, 2013 If you plan to autocross and drag race, an argument could be made in support of an automatic since autocross tends to be a 1-gear event. May go auto someday just to be easier on parts. Quote Link to comment Share on other sites More sharing options...
