RUMOR CONTROL: The notoriously bad Ultradrive caused by Iacocca's bladder?

There's a rumor that has been circulating since the '80s about the 4 speed A-604 "Ultradrive" disaster that slung mud on CC at a time when it didn't need it. Pro-Chrysler forces blamed the oil companies and GM's roll-out of Dexron II, whereas the 7176E Chrsyler spec (ATF+3) was the only option for the A-604...AFTER all the trouble started happening. However, enough time's gone by to say with authority that there were MANY engineering bugs in the rollout year of the 604 that persisted for years. Here's the rumor...anyone heard it?

Supposedly, in a development management meeting in Auburn Hills, the subject at hand was the A-604 project, which was having tons of developmental problems. Engineering didn't want to put the thing in the new lineup due to reliability worries, but marketing said they were losing a ton of sales, since GM had already put their four speed

4T60 to go into its '86 "downsized" B-O-P cars, and the 4T80E in the new FWD Cadillac de Villes. Chrysler was still stuck with its A-413 3 speed and the A-904 for what was left of the M-body lineup. GM's B-O-Ps were turning in impressive (for the time, anyway) EPA highway figures, which CC couldn't match with the A-413, unless using instead (as with the RWD M-cars) unacceptably tall final drive ratios.

Iacocca was, of course, in the driver's seat, and after hearing a rash of arguments as to why the A-604 couldn't make it for production next year and counter arguments as to how GM was kicking their asses in the FWD upscale market, he allegedly said to his people:

"I'm gonna go take a piss. When I come back, this goddamned thing had better be in production...."

True or false? Or at least...has anyone heard this in the old CC dealer organization?

We plan to challenge Mr. Iacocca to confirm or deny this rumor once and for all, but I need to know "who heard what when and where" first.

The word on the street was that Iacocca was in need to cut costs so that he could earn his performance bonus. So he fired a number of technical development members, and outsourced the development of the electronic components to the new transmission. I don't know if this is true or not.

All you have to do is look at a Chrysler transmission manual for the A604 and see the list of design changes that are recommended for rebuilding old transmissions to prove this.

Understandable - it was their first electronic transmission. This doesen't have to be proved.

I don't know what engineering was saying on this, but once more, the marketing side was obvious. All you have to do is look at the target market for the minivan to see that overdrive was non-optional for the van to be considered for purchase by it's target market.

What other overdrive option did they have than the A604? At the time, nothing.

I don't see much point in proving this. The first V6 introduced in the minivan line was in 1987, (Mitshitty 3.0) and the A604 didn't come along until 2 years later. Chryslers marketing had at least a years worth of sales data to show if the

3 speed automatic V6's were going to be accepted or not. The 3.3 didn't come out until 1990 and it and the 3.8 only mated to the A604. If customers had demanded the 3 speed automatic in '87-'89 then Chrysler would have made it an option for the 3.3 and 3.8. The 3.0 and 3.3 have the same A604 bolt pattern there is only one difference where the oil feed is so it would have been simple to do it. The fact they didn't wasn't an indication that they were stuck with the A604, rather that they chose to use it.
