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.

  • ToolGuy Let's count the poor decisions: Honda 18 model years past peak Honda. Ohio. Following too closely ('rock on the highway' doesn't leap up and attack your vehicle by itself, it is riding on a vehicle or thrown up by a vehicle, and you should be alert to this). Ohio. Not enough doors. Choosing to expand family -- in Ohio. 😉Engine bay picture: At least take a shower before your glamour shot lol.
  • ToolGuy Took me a minute to post; had to go back and see which account I was using the last time I commented on this topic (consistency is important). Thank you for your patience.
  • ToolGuy Ok wow, just wow. I used to live in America. Land of the free -- have I heard that somewhere? And here come TTAC writers and commentariat goose stepping in lockstep, dancing on the grave of liberty. Didn't your dysfunctional homeowners association get all that government overreach out of your system? I thought we won WW2, guess I was mistaken.
  • Dartman If one is so hellbent on drawing attention to themselves just mount a big “Trump 2024” or “Black Lives Matter” flag (your choice) on your truck and call it day. Lot cheaper, same result.
  • AZFelix I'd buy a 'harlequin' edition if it was composed of a company's complete palette of greys and silver.Family had a couple of Pontiacs in teal and purple in years past. I was not a fan.My current ride is Lakeside Blue.
