62TE Intermittent Failsafe!
Occasionally the van was going into failsafe and setting codes P0733, P0734, P0792 and P1790. The Low Compounder Bonded Piston had come apart in a section. We could never get the fault to happen on our watch.

We didn't find the piston problem until we were rebuilding the unit. The dealer had an updated piston to go along with the updated Low Compounder Drum that came in the Mopar kit. The kit from the dealer was really something. It comes with the Underdrive Piston Housing (we replace a lot of those), a new Low Compounder Drum, the nut for the Transfer Shaft, the flow control valve, a filter, and even pump to case bolts and converter bolts. Some of the notable items not in the kit are all the bonded pistons and the low reverse piston housing. The Master Kit with Steels was $274.30 P/N 68272623AB and they had it on the shelf. 68272622AB for Banner Kit Less Steels $258.70 and 68272621AB for an Overhaul Kit $137.80 (all these should come with those extra goodies). It was cheaper for me to get this through the dealer than a Kit L/S, Low Drum, and Underdrive Piston Housing through Transtar. We might have to check out more of the dealer kits in the future. - more
