|The specification for the transmission fluid recommended
by Dodge for the NV-5600 6-speed manual transmission is Chrysler Part No.
4874464 (Specification MS-9224). The price for this fluid
from the dealer is ..., well more than you want to pay.
Until recently, the fluid was made by Texaco, and was only sold in bulk
quantities with the Texaco label on it. After reading some posts
on the TDR on this subject and doing some research, I found that I was
able to order the fluid from Pennzoil in 12-quart case quantities for less
than $50/case plus tax. The Pennzoil part number for the fliid
is 3501. I ordered a case from the Pennzoil Distribution Center
in Tucson and received it in four days and did not pay any shipping as
I picked it up at the distribution center.
If you are having trouble locating a source for the fluid, you can call
Pennzoil at 800-468-6457 and ask for the phone number of the distribution
center in your area, and they should be able to get it for you.
Some AutoZone stores also stock the Pennzoil Synchromesh fluid, but
availability is limited.
Note that this fluid meets the Dodge specification for the NV-5600,
and is not a lubricant from some other application that you are experimenting
with. Good luck and happy shifting.
