Re: [ihc] Limited slip additive in automatic

[Christopher DesPlanques <kd7cpz@xxxxxxxxx>]

This probably doesn't apply much to IHC 727, but I ran
across this regarding fluids in computer controlled
Mopar trannys:

If somebody puts DEXRON in, take it to a shop which
uses [the right fluid], and have them drain the ENTIRE
transmission, and refill with [the right fluid]. This
will cost about $160.

WHY? The friction characteristics of DEXRON are
different from [the right fluid]. It is a "grabbier"
fluid. The Chrysler transmission has an electronic
system which continuously senses the behavior of the
transmission and regulates shifts accordingly. If
DEXRON is used, the clutches inside the transmission
will "grab", and the electronic controls, which sample
the operation of the transmission about 140-180 times
a second, will let up on the clutches. The clutches
will then slip excessively, the transmission will try
to tighten up on them, and due to the characteristics
of DEXRON, they will again grab. This will occur at
the 140-180 times per second rate, and the
transmission will have a shuddering feel to the
shifting. This is also very hard on the clutches, and
they will have a short life. The cost to overhaul one
of these transmissions is about $1200-$1400 on a
front-drive car, so you DO NOT want to shorten its
life.
