TRNW-2: UB80E question.

[Chris and Cathy Kershaw]

Ours had tcc codes & pump whine. Lots of black stuff in the bottom of the
case & in the filter. All the friction in the trans looked great. We did a
dealer vb, came with solenoids and a recon converter. It’s all ready to go
back in just haven’t installed it yet.
