My 90 T4R sr5 (22re 5spd 4wd w/ 31" tires) had a catastrophic engine failure about a month ago which lead to a motor swap. I sourced a very nice 22re with about 27,000 original miles on it from a dolphin (motor home). Since the swap I've put about 60 miles on the truck and I just noticed a major problem with my 4wd system.

In 4 low im slipping bad.. I shouldn't say slipping because it implies a clutch problem, but that's definitely what it feels like. If I dump the clutch in low I get initial 'grab' but then the rpms come up like hell but the truck doesn't go any where like the clutch is slipping. In 2wd or 4Hi it doesn't seem to replicate the effect. Any thoughts?

As some quick background info... With the motor swap a brand new AISIN clutch kit was used (rockauto.com AISIN Part # CKT022 ) and a new bruteforce flywheel. I honestly don't know when the last time the Transfer case fluid was changed so I'll be doing that tomorrow, but as of right now I know it is full. Also my 4x4 indicator like no longer comes on but Ive verified that the ADD axle is engaging, the hubs are lock and I am getting power to both front and rear wheels.

I cant stand to redo work so Im hoping some one has some insight that doesn't involve me having gotten a bad clutch kit from the distributor.

Any and all input appreciated.
