One more quick question, do ALL the gen 2 cars have the speedo pickup on the tail shaft? Or did it change in 2001 with the abs cars? I was told that since I have a 2001 I don't have to mess with the speedo issue in the tail housing?
The output shafts are the same size. The YOKE diameter however is NOT. You cannot swap tail housings either as the cluster shaft bearing is secured differently.
The gen4 drive shaft is about 1.5" longer. Just picked up my tr6060 and drive shaft on Wednesday. You would not believe HOW NICE this trans shifts out of the vehicle. I cant wait to feel it while driving.
The reluctor wheel is a different story. It does not fit very tight on the output shaft so I am curious how everyone is centering it up and keeping it true?

Just wanted to update this that I was wrong on the tail shaft seals being swappable. I edited my last post so if anyone searches later their wont be any confusion.
I completed the retro-fit of the gen 2 speed on my 6060. I had to create a shim to center the reluctor wheel on the smooth output shaft of the 6060. I put a few tack welds on each side as of course this wheel would need to be removed if the trans needs servicing. The housing was faily simple but you cannot recreate the sealing oring machined into the t56 tail housing. You need a drill bit that is .700" to get the perfect hole. I put some grey RTV on the sensor and the bolt to seal the sensor up.
Also a heads up the local parts stores to me do not have the correct listing on the tail shaft seal. This seems to be a dealer only item at the moment...
Ill throw some pics up later of the speedo retro-fit.
First their are 2 tabs/ears coming off the passenger side of the trans right behind the sensor. They have to be cut down atleast a half inch or the trans will not fit up in the tunnel. They were contacting my passenger side tunnel frame and preventing it from coming in towards the motor any farther. Also when and if I have the trans out again I will probably be knocking a couple of the other tabs that are on the casing to ease installation. Most of those tabs are for the chevy bodied cars so their not needed in our application. The transmission is larger and longer so it takes some work to slide it up in the car.
Second the transmission mount must be notched ~3/8 of a inch to bring the mount towards the front of the car. I have a billet crossmember which already has the center bolt notched out which helped allot. Like i said the trans is longer.
The old t56 shifter just pops right on to the trans no issue. I did not note any differences in shifter location as Todd did. But I dont have a second viper to compare it too and the trans had been out of the car for a month... -To note I do have a B&M shifter with a brass base cup.
Driving notes - The shifting of 1st through 6th is amazing. Like butter smooth. Literally takes one or two finger to just toss into gear. Reverse even seems easier to get into which was the one thing I hated on the t56. Only time will tell if this trans will take the abuse I put my t56 through....
