I've got a Tremec TR-3450 that I'm going to put in my S10.
Is there a parts breakdown available so I can see what all I
need to get in order to get it hooked to the engine? I don't
know this stuff by heart (yet). Thanks!

 

what did the 5 speed come out of? what year . . .?

I had a 5speed in my 92 1/2 ton. It was a gethdrag. hunk of junk

you could always check out the 6speed swap thread.

I'm sure that you'll need the 5speed x-member, pedal, clutch master cylinder . . . . the thread has the part No. that you'll need.

 

My S10 was a 5-speed, so it's got the pedal, a master cylinder, etc.
I was actually more interested in the internals (clutch, bearing, etc).
I'm curious what all I need to button up the tranny to the motor.
