This post deals with swapping a WC T5 for a NWC T5 in my otherwise stock 4.57 geared 1951 3600.

I documented my T5 conversion here; https://www.stovebolt.com/ubbthreads/ubbthreads.php/topics/1149777/My_T5_conversion.html#Post1149777

Due to my mild case of OCD I haven't been happy with the whine from the 1352-146 transmission I used in my 5 speed upgrade. A new input shaft and bearing helped and I'm sure the tranny would likely run forever but I'm trying to make my stockish truck as quite a daily driver as possible.

So, in the past week I've picked up two additional T5s, a 1352-193 and a WC 1352-222 out of a 93 S10. Last evening I cleaned and pulled the top/tailshaft off the 222 unit. HAPPY to find it had not been opened up since leaving the factory in 93. Still had red thread locker on the bolts and the sparse Ford black sealant in place. No odd stuff in the case, only a small coating on the magnet.

So now it's pull the 146 unit from the truck, swap the speedometer drive gear for the electric speedometer reluctor, mod the input shaft and bearing collar and try it out.

Without having the NWC 146 next to the WC 222 it hard to tell, but my only concern is the much larger 5th gear bulge in the WC 222 tailshaft. Makes me wonder how the NWC tailshaft will fit.

All the above has been done and documented so hopefully it's just a swap out parts deal...Time will tell.
