Transmission in the kit is actually the New Venture 5LM60 5-speed.
Trans you added is the TH350, if you have any of the SS454 kits you could have used the trans out of that (4L80E, but close enough)
Though the kit trans was the SM465 4spd available from '88-'92 (the kit being a '90), also like I said this trans is parts box, and I really Don't care, looks better than the 4spd manual trans, Only external visual difference in 25th scale is the pan, which I'm not going to bother screwing around with.
I always love the clean looks of the Scottsdale.. I use to have a 94 Cheyenne but now I have a 91 GMC SLT nice trim pack but I almost wish it was the SL ( now that some of the trim is had-it ) and I have a 93 Bravada ( I wish there was a model of that ) but my Cheyenne had a diff grill and headlight (it used the sealed beam headlight like the older cars/trucks ( one on each side what we called the plain jane nose )) so it through me off when I seen the pick of your pickup..
My Cheyenne has the Composite lights and chrome Grill from the factory, was a available "Decor" Package at a cost of If I remember right $115.
