is there a way to tell on by lookin at it, i know the obvious way is to drive it but right now the motor is blown, please help

 

Well, I think that H/A didnt make an cable GSR tranny, so right there, if its a hydro that eleminates that. Unless they took the LS tranny apart and put the GSR guts in it. The Clutch cable type LS says S1 on it.

They did make a cable GSR tranny in 93 i believe. The tranny i have is a 96 GSR(hydro) it says Y80 hope that helps

 

well its a hydro tranny, im trying to identify the difference between the newer ls and the newer gsr tranny

 

my gsr tranny is an s80? 98 too

 

can't tell from the case, or the S/Y80 on the case. Only way to tell is either to put it in first and rotate the input shaft and count how many times it turns compared to the output shaft. Do some math on the known GSR and LS gear ratios to figure out the same. Could also use reverse since it is a 3:1 ratio, and just do the math on the 4.40 and 4.266 FD.

now there's a excellent piece of advice

 

How do you put it in gear if it's out of the car?

 

by using the shift shaft

 

So the S80-3002780 means nothing?

 

Nope.. the LS/GSR/Type R trans case is all the same.. and the LS/GSR will some times both say S80 or Y80.

Your best bet is checking the VIN tag. If it starts with JH4DC2, it's a GSr tranny, if it's JH4DC4, it's an LS.

Not So Nice Guy's info will also help you.
