C4 Corvette LT4 Transmission
Hello All,
I have a 1996 corvette with the 6 speed manual and LT4 engine. I am going to be parting it out soon and want to be sure I list everything correctly.
My question is what the transmission code is? Is it the same as what comes in the LT1? I did a search and only seemed to find it ever referred to as a 6 speed manual, can't figure out anything more about it.
Any help is appreciated. Thanks! 🍻

There are a few different versions of the ZF-6.
The ZR1 has a different length input shaft.
The early L98/LT1 cars have a different diameter input shaft guide tube (Can be swapped between transmissions) (needs different throwout bearing to match diameter)
The early cars have a different speed sensor (Can be swapped between transmissions)
The shifter on '95-'96 is a "crash through" design that is different from the '89-'94 lift ring for reverse. I am not sure if it is only the shifter or if there are differences in the transmission too.
I agree with FrankieD that the ZF doc website has a lot of good info about these transmissions.
1-15-24 update:
I also forgot to mention the '96 is a blue tag transmission. The earlier black tag transmissions have a more square cut gears and on paper has a higher torque rating. In practice I have not heard of a real world difference in strength. The black tag may be a little bit louder gear noise, but I have owned both and could not tell a difference.
