Comments about Dorman - OE Solutions Automatic Transmission Cooler Line:

Had a really hard time getting it to snap on the transcooler on the radiator side and I tugged on it and it wouldn't come off or leak and then it popped off as I was driving it and lost all my fluid and started slippin before I got to work so hopefully I didn't burn up my transmission


Buy the correct line - this isn't it!

About Me Mechanic

Comments about Dorman - OE Solutions Automatic Transmission Cooler Line:

Bought this and the corresponding line for my '01 Cherokee XJ while I was installing a two-row radiator. To slide properly into the fittings on the AW4 transmission, the line must clear an ear that routes around the torque converter and block ear. This line is not bent properly and is not long enough - you CAN press the line into the fitting, but this requires a great deal of force and puts the plastic quick disconnect fitting under axial tension. This is very likely to fail quickly, resulting in a loss of all pumped transmission fluid in a matter of seconds with no warning whatsoever.

Additionally, the first of these lines I received was bent 90deg prior to packaging - you can't rebend a steel line without structural fatigue and reduced flow capacity.


Perfect Fit, Great Quality

    • Q:

      is this hose that to the bottom of radiator?
      Asked on 12/29/2014 by eric from lafayette,in

        Hi Eric, I'm glad to help you! This hose goes to the inlet from the upper radiator tube. If you can tell me your vehicle's year, make, and model, I can suggest parts for lower radiator hose available for that vehicle.
