Engine/Transmission (1998.5 - 2002) automatic transmission cooler plumbing

[waltk]

I am interested in seeing a clear photograph (or better drawing than the service manual shows) of the factory-plumbing associated with the oil-to-water tank-type transmission cooler. My desire for this view is to assess feasibility of using the coolant flow circuit normally intended for trans cooling to permit plumbing a coolant filter. My trucks are manual transmission and have all space which would have been occupied by the cooler available for use in mounting and plumbing the filter. Also, if anyone knows whether the cooler return hard-line is a Chrysler part or a Cummins part, that would be greatly-appreciated. Lastly, if I deem it reasonable to proceed with this installation, I may make a follow-up request for an engine serial number for a 1998. 5-2002 automatic truck. Thank you in advance. (and, yes, I will document the process, if I elect to proceed). Important to note: my question focuses installation of a coolant filter in a manual transmission truck using the coolant flow-path normally associated with the automatic transmission cooler.



Regards,

This is the torque converter cooler plumbing for the 98. 5 that I used to have.



Notice the second illustration shows the tee needed to share heater coolant flow with trans cooler on the return side.



All items shown are available as Cummins Part Numbers.

Mike, many thanks! My idea is confirmed. By chance, do you have access to the part number callouts for these illustrations?

No problem, I can provide them.



I have no luck trying to bring the Cummins part number listing over onto the TDR as it simply jumbles it.

One of these days I will figure out how to do it... ... .



You can provide the key numbers from each illustration for me and I will post the current part numbers for each.



Or if it would help I can try to print the parts list, scan and e-mail it to you. If you prefer that please send me an e-mail so that I can attach the scan to the return mail.

Let me know.

Moving ahead with coolant filter "Done Right"...

Mike,



Many thanks for the information. I just ordered the necessary plumbing to "misappropriate" the coolant flow circuit usually-devoted to automatic transmission cooling (in the Dodge application) for adding a coolant filter to my truck. The procedure and process will be appropriate and applicable to manual transmission equipped trucks in model years 1989 through 2002 (perhaps beyond, but I have not studied 2003 and newer in sufficient detail).



Warning, there is a price-premium in using genuine Cummins and Fleetguard parts rather than purchasing a third-party-assembly. My goal is to show the use of parts and supplies that are likely to have a long-term durability and availability that is worthy of installation on the Cummins engine. My parts-cost, to-date, is approximately $325; third-party pricing seems to be around $125-$200...



I will make detailed instructions and bill of materials available when complete.

On my 98. 5 we just used some high pressure hose and mounted a spin on Oil Filter base under the radiator.

Cost was minimal, it has been there for 6 or 7 years. We just use a common engine oil filter for the job. I change it out every time i change engine oil, top off the transmission a bit and off we go.

KISS does it for me.

Yes, *KISS* is best and next-best is KISS-based utilization of factory components. I think you may have misunderstood my goal. I am not adding extra transmission filtration; I am adding coolant filter and plumbing into the coolant-loop normally used for automatic transmission cooling. The bad news is my solution is suitable only for manual transmission trucks.

Oops, didn't follow the OP close enough or look at your transmission type.
