Re: [Chrysler300] First law of hydraulic systems

Rich,

There is absolutely no reason to cut a hole in the floor to get to the kick down shaft seal. Anybody that would cut a hole in the floor to do a simple job should not be working on cars. I have done many of these seal jobs without removing the trans, or cutting anything.

The speedometer gear has an internal seal, and an O-ring around the parts that goes into the case. If these were changed when it was “overhauled” properly, it should not be leaking.

As per Fluid mechanics Professor: The first law of hydraulic systems is that hydraulic systems leak.

Our 300K goes into the tranny shop to assess and cure bad leaks from the newly-overhauled unit. Previously, another mechanic observed both the selector cable and the speedometer cables were leaking. He was able to heat-shrink-wrap one of the cables, but not the other due to the end device being too big. I robbed my parts car speedo cable and will have it heat-shrink-wrapped and installed. My restoration guy says there is a mechanical (kickdown?) arm on top of the tranny that was leaking, but it was inaccessible while the tranny was in the car. He then created an access hole in the front floor to assess and address any leakage from that point. I’ll keep you posted and ask that you pass on your findings as to source of leaks.

Subject: [Chrysler300] Engine mounts and 300H Transmissions Al 727

I picked up my car this morning with its replaced engine and tranny mounts . I had an NOS RF and a used LF, plus a new tranny mount from Jeff Carter. The reason I changed them out was that

I believe the engine wassitting too low which is hopefully why my fan blade was clipping the lower part of the shroud which happened after I changed out my fan clutch!

I was very surprised at the difference the "new" engine mounts made in terms of smoothness of idle ??? All I can imagine is that the engine rocking around was modulating the throttle linkage.

But now there's another issue to be resolved. transmission fluid leaks.

My mechanic (in the top 20 of 1900 in the Bay area) added dye to the transmission this morning.

Tomorrow morning we will look for leaks on his rack.

Does any one have suggestions for the most common source of leaks?

Also, if it does have to come out and go to a shop he recommends to be resealed, does anyone know, or is there a club publication

about the differences between a 727 and a 300H 727? (I am anticipating a call about needing a rebuild etc. I really do trust this shop, even though the owner is Corvette afficianado :-)).

Thanks for the help.
