T56 info

[HICKL]

I'm all over the place on this tranny thing. Missed out on a good deal on a G-force T5, now I am thinking along the lines of a T56. Can somebody give me some pros/cons on the T56? How much power/torque can it handle, how hard is it to fit into place following a T5?

 

I want to make a move pretty fast, My car is feeling pretty strong with the tunnel ram on it and I know my freshly rebuilt T5 is just gonna fail again if I drive it like I want to.

 

Thanks

Jeff

This site has a ton of info on transmissions

They make an aftermarket t56 that should bolt up to your exisiting set up. The aftermarket ones even have mechanical speedo hookups. If you go used, you will need to get one from the LT series motors (pre 98?). the LS motors have a different mounting set up. Keep in mind the older T56's seem to need shift forks at some point in their lifes, and the T56 rebuilds are rather expensive. This place is highly regarded on LS1TECH.com and has rebuild packages starting at $900 and up

Another option is the TKO. They make a GM version that I bolts up to a standard SBC bell. The transmission places I talked to seem to think a lot of their durability. Their 600 ft-lb rating exceeds the values on the OEM t56's.

 

You can do a search on G Force T5's. Suppose to be strong. some people have had troubles with G Force salesmen. One other member complained that the tranny was very loud. Sort of the price you pay for gears that are more straight cut.

My T56 will bolted right in with four caveats: I used a Weir bellhousing (which included a hydraulic t/o bearing, much improvement over the external on a T-5); I moved the motor forward about 3/4", though still inside the "slot" I created in the Z mount-points per JTR; I moved the JTR tranny mount back about 1"; and I beat the crap out of the top of the tunnel by the bellhousing. With the 3.36 rearend the gear ratios are fine (I"m not a quarter-miler kind of guy), the action is smooth, and I *love* the 6th overdrive. The change from the T-5 *did* move the CG back enough that I notice it in spirited driving, but not a problem as I've tuned the car to understeer; it made it behave closer to neutral.
