Abandoned History: The Chrysler UltraDrive Transmission (Part II)

We finish up our Abandoned History coverage of the long-lived UltraDrive transmission today. The pursuit of simplification, modernization, less weight, and better fuel economy lead to the creation of the electronically controlled four-speed A604 marketed as UltraDrive. The idea floated around at Chrysler in the Seventies and then was greenlit and put into production (before it was ready) by an eager Lee Iacocca. A case of unfortunate timing, the new transmission arrived in 1989 at a time when there was almost no exciting news in Chrysler’s product portfolio. Thus the UltraDrive name was coined by marketing, and the new and advanced transmission was featured heavily in the company’s PR materials in 1989 and 1990.

The UltraDrive’s debut version was prone to numerous types of failures because of fluids and sensors, build quality, parts, really everything. But engineers at Chrysler quickly massaged the A604 into the improved 41TE that was ready for use midway through the 1990 build year. UltraDrive was up and running within acceptable reliability standards per Chrysler. Clearly, it was time to create more UltraDrive variations!

Ford Can Sell Expensive Pickups As Long as They Aren't Lincolns (Except in Mexico) – the Blackwood and Mark LT

GMC just announced an Ultimate trim level for the Sierra pickup truck. That follows Ford’s success with Platinum-level F-150s that can cost up to $80,000. It seems that nowadays you can’t charge too much money for an American pickup or make it so luxurious that it won’t find an eager market.

It’s tempting to say that wasn’t the case in the early Noughts as a means to explain the failure of the Lincoln Blackwood. In production for barely a year, the Blackwood was the automotive equivalent of a TV sitcom getting cancelled after just the first episode. Ford hoped to sell 10,000 Blackwoods a year, but managed to move only 3,356 for its entire production run.
