I've rebuilt a couple T18's and it's not real tough, but you need some basic tools like a bearing puller and a press to put them back on. A complete rebuild set of bearings and thrust washers runs about $150. Check
www.novak-adapt.com for the kits.
Kit #SP465 $158.
SM465 Small Parts Kit consists of: all seals, bearings, bushings, snap rings, keys, spacers, thrust washers, oil baffle, retaining pin, seals, gaskets and instructions
What confuses me is you say the countershaft bearing is going out? Every tranny I've ever seen has a few dozen loose roller bearings for the countershaft/cluster gear.
