Wouldn't hurt to check fluids running at operating temp, and do a drain and fill(a lot of debris gets in there when you start working on them) inspect oil ect, any findings show to builder, confirm you have some regular old dex3 or similar, hopefully they used a OEM filter. Your description reminds me of driving in 4Lo, so maybe check all those fluids are good before visiting the tranny shop so ya don't look like a chump that forgot to check the t-case for the past 19years. Did you do the install?, if so all alignment pins in place, everything tourqued to spec
