1981 SX/4 transmision swap
« on: December 08, 2015, 10:15:26 PM »
I have a 1981 SX/4 Iron duke with the SR4 manual transmission has any one swapped it for the 5-Speed  T5 Transmission  I would rather put a 5 speed in the car than fix my 4 speed. Any suggestions to the swap ?

Get the bellhousing, etc from a Chev S10. IIRC, it's an SBC or 4.3L V6 pattern?

Well I went ahead and had the 4 speed rebuild . I didn't want to mess with doing a swap . I just wanted to get my Eagle back on the road! Its a world of difference in shifting with the new clutch , rebuilt the clutch pedal assembly!

I don't really have any experience with it, but from what I've heard the 5th gear on the T5 is basically useless. So maybe it's a good think you just had the SR4 rebuilt. Glad it's back on the road!

Useless in what way?

I've heard that the 5th gear can basically only be used at speeds over 70 on flat ground or going downhill. Like I said, I have no experience with this I just recall others talking about it.

Don't know about the SX/4, but on my wagon (258 with the 5-speed), I routinely shift into 5th at around 55 mph.  Works pretty well.

Yeah with the little Iron Duke does alright but it for sure doesn't have the pull of what the  258 does.

Ah!  My mistake... I didn't realize that we were talking about the 4 cylinder.

It depends on the gears and tire size whether 5th is useful or not.
