NEW Viper T56 6-Speed. Use to retro-fit into GM cars!

Details:


This transmission can be used to convert your car into a T56 / 6 speed pavement pounder! It comes with an adapter plate so it can be bolted to any GM 4 speed bellhousing. If you got a monster 350,383 or 406 small block this is the transmission for you. Has a mechanical speedo housing that ueses any muncie 4 speed speedo gear set. This works get for the 82-89 Camaro's. Please feel free to call if you have questions. We have installed this transmission in a 70 Chevelle with a 502. Works great!

im worried about the 4spd bellhousing, i have a 700r4 is the 4spd anywhere close to the 700r4 bell or the lt1 bellhousing? i guess it uses the same clutche assembly and slave cylinder as the lt1. i know the lt1 T-56 is 2inches further back does the 2inches further forward on the viper trans mean no cutting? any info on this would be great

 

the 2" is referring to the shifter being placed farther toward the rear of the car. Unless they have modified the tailshaft housing to bring it where the f-body location would be. Since it comes with a mechanical drive for the speedo, it sounds like they have installed a JTR housing. The viper trans is an excellent unit but has alot of costs of getting the right parts to make it work correctly. A 4 speed bellhousing will bolt to the block.

I was under the impression the viper uses a larger clutch than the vette or camaro.

 

I can answer your questions about the bellhousing information. The adapter plate allows you to use older style (1955-1992) bellhousings, that use a standard 4 speed mounting pattern. pretty much any GM car out there, and some ford and Chrysler.

you have three options, basically:

-use a standard GM bellhousing, like a chevelle or normal pasenger car, which are readily available. This presents a problem because the camaros with manual transmission used a canted fork (down 15 degrees), to clear the floor. So you could use a 3rd or 4th gen clutch master cylinder, with a custom line, and use a hydraulic throwout bearing.

-use the 3rg gen bellhousing. this presents a hassle because the trans pattern is canted 15degrees. so you will have some trick stuff to do to mount the trans mount, plus, the trans wil lean, which may make the shifter akward. you are OK with the hydraulic slave (or mechanical early 82-84) clutch linkage though. A corvette bell will also work (84-88?)

-use a blowproof bellhousing from lakewood, for a 3rd gen camaro. good news all around, except they cost more money, usually, than the other two. They have the fork canted, so it clears the floorpan, and have both the 15 degree pattern, and a straight pattern for the trans, so you can mount the trans straight up. this will also use the standard 3rg gen hydraulics (or early mechanical). a plus is that it is steel, which is always better to house the clutch in case of problems.

have fun!

 

1981 it says further forward. that means toward the front of the car. it says retro fit so i guess they modified it some.

JWS your saying i can use the stock 700r4 bell housing right? if thats so all i need is the slave cylinder and master cylinder and the lines, pedals and that yoke. and maybe that modified cross member i can find that out from fbodymotorsports.

One question can i use the stock drive shaft with that adapter plate i know it will push the trans just a little backward but would that matter?

 

As I found out, if you have a 700, then you dont have a single part for the trans swap (which is a suprisingly large numbe of parts). The 700's case is all one piece. No bell housing like what you have with a manual trans.

As for the shaft, it should be ok if the trans is the same length as the stock one you have currently. At the very least, though, youll have to change out the yoke.

 

like dimented said, the 700r4 has an integral bellhousing, meaning its all one peice (side note: the latest model of the 4l60E/65E have a modular housing, but your car doesn't).

you would need to buy everything. bellhousing, clutch, flywheel, clutch master cylinder, pedals, shifter console (or modify yours), and of course, a new driveshaft (you might be able to shorten yours, but you need a new output yoke which may not use the same u-joint.)

one other thing you need to concentrate on is the torque arm, since the factory mount is part of the trans, you will need to make one that mounts to the crossmember. they probably offer one that has everything you need. I'm not sure how the retro-trans deals with it.

its more involved that you might think, so make sure you do research. and save up some cash. it easily gets expensive.

but it sure is fun when its a stick!

 

i asked fbodymotorsports how much all the extra parts would cost together they said $700 thats including the hemi style yoke.

they didnt say anything about the clutch and flywheel not working from a lt1 so i guess it will.

if i can afford ill get the viper trans if not ill settle with the basic T-56 . i can get the pedals,yoke,master cylinder, bellhousing ect.... from the same place as the trans. i figured up 3600 for everything. a lot of money i know but i figured it will work better with my motor once i get it built. the gear ratio's will work better and it can handle the torque im wanting.

 

just judging by the pictures of the trans the torque arm mounts up the same on both T-56's as for the drive shaft the plate probably isnt more than a 1/2 inch thick. i know when i took my drive shaft off for the rearend swap that i could slide it quiet a distance forward and backward you have to slide it forward an inch to detach from the rearend so i think it will work if not good excuse for aluminum driveshaft

 

I just swapped the 700R4 for a Tremec TKO 600. All the parts new cost me $3000 including pedals, hydraulics,Mcleod bell, clutch, flywheel, DS yoke, etc. The TKO 600 is rated for 600 ftlbs torque & 650 hp. More if you get the optional case girdle.
