T-56 Install

flywheel- depends on what condition yours is in. if its decent resurface it and keep using it. if u have the $$ to spend get a nice alum one.

Having done the Viper T-56 swap in my GTS, I can chime in on a few of these.

1. Would i need a system to tell how fast im going and for the mileage?

My stock speedo cable bolted right in after I moved it over to the opposite side. The speedo hole in the tranny is on the opposite side as the T5 so it had to be rerouted. Other than that, I swapped the gear to compensate for the viper gearing and it was fine.

2. I read theres a reverse lock up. that i need to use for reverse. Is this true? If so how is it done?

Yup and there's a couple of ways to go about it. One, you can remove the solenoid completely (IIRC, it's held in with one bolt) and bolt plate over the hole to keep dirt out. Two, you can build up your muscles and manually override the solenoid to get it in reverse (it's strong, but not too bad). Three, you can wire the solenoid into the brakes (with a relay) so that when you step on the brakes, the solenoid retracts (that's how the T56 Cobras and Vipers do it). I was going to get fancy and build a box that read the speed off the VSS and automatically disabled it so that it would only engage at 0 mph, but never got around to it.

3. Should I use the stock flywhhel or should should i go for aftermarket? I might get a spec 2 or king cobra clutch not sure yet.

You've got it open so you might as well swap it out. If $$$ is a concern, just do an inspection and call it good. Since it's a brand new tranny, I'd at least swap out the pilot shaft bearing (located in the back of the crank).

4. Do i have to adjust my clutch since ill be installing a new one.?

You shouldn't have to. I swapped to a McCleod street twin so there was some massive adjustment issues with my swap. But keep in mind that I was adding about 1/2" to the clutch thickness.

5. Any other things i should worry bout?

Exhaust. My Bassani offroad X needed some major fabrication. Being the stubborn ass that I am, I opted to build a new crossmember instead. Other than that, the majority of my problems were all due to the street twin clutch so you should be allright with a stock type clutch setup.

thats what i do

i reused my vss---if i remember right you have to move the entire harness for the tranny to the other side.

might as well put in a good flywheel, clutch, cable, etc... while your there. especiall if you are flat-backin it---that tranny is pretty heavy and you don't wanna be pullin that thing in and out all the time.

no you need a relay...a relay will prevent you from blowing fuses and/or burning up the wire or even your car by drawing too much current from a small brake light wire. the brake wire is connected into the relay which uses a small amount of current not enough to blow a fuse or cause a short or fire so when you push the brakes a small amount of current will enter the relay causing a set of contacts to close these contacts will be connected to an alternate sufficient 12 volt sorce that will activate the solenoid in the tranny to allow you to place it into reverse....a fuse itself will cause problems...

look at the relay in this link just look at the relay pin numbers dont pay attention to anything else...http://www.ado13.com/techs/relay.htm ...ok there is 4 connections numbered 85,86,87,30...ok 30 will go to the battery or a sufficient 12 volt source and 87 will connect to the tranny relay which has 2 wires the second wire on the solenoid will be grounded to the body or sufficient ground source.85 will go to body or sufficient groung source and 86 will connect to your brake light wire....

no problem...glad to help..check with D&D performance at 248-735-6220 about the speedo gear they can sell you what you need and answer all of your questions there very knowledgable about trannys. they sold me the parts and told me what i needed to know about my TKO500 tranny install....heres there website. http://www.ddperformance.com/

Guero, as Bill said, a relay is just a high-current switch. Their ability to be remotely located is nice. E.g., The solenoid on your starter is a relay - otherwise you would have battery cables running through your interior to your ignition switch.

In case it helps when buying a relay, the relay in Bill's link is a Single Pole Single Throw (SPST) relay. You can also use an SPDT (D=double) relay instead - just don't use the 5th (87A; Normally Closed) terminal.

Any stereo shop or Radio shack should have SPSTs and SPDT's. I would use a fuse on the wire going to the common terminal (in Bill's outline, terminal 30).

Good luck.
