Transmission cable assembly for high temperature environments

An automotive transmission shift cable assembly comprising, in combination:

• a conduit subassembly comprising a conduit and a core wire extending through and beyond the ends of the conduit,
• a shifter end portion, and
• a transmission end portion,
• wherein the conduit subassembly extends from the shifter end portion to the transmission end portion, and the transmission end portion comprises:
• a core wire length adjuster comprising:
• a generally annular, soft plastic core wire adjuster isolator forming a central bore having a connector pin socket portion and a retainer cap socket portion, and comprising polyester-type thermoplastic polyurethane compound, and
• a retainer cap configured to be partially received by the retainer cap socket of the core wire adjuster isolator and having a connector pin end socket configured to receive and engage a portion of a connector pin received into the connector pin socket portion of the core wire adjuster isolator, the retainer cap comprising 25%-50% glass-filled Nylon 6/6, wherein the retainer cap and the core wire adjuster isolator have corresponding configurations operative to interlock with each other when a connector pin is received into the connector pin socket portion of the core wire adjuster isolator and the connector pin end socket of the retainer cap, and
• a conduit end fitting comprising:
• a sleeve on an end portion of the conduit,
• a conduit end fitting isolator over at least a portion of the sleeve and comprising a polymeric silicone compound,
• a conduit end fitting cap over at least a portion of the isolator,
• a conduit end fitting abutment over at least a portion of the conduit end fitting isolator and engaging the conduit end fitting cap, and
• a swivel tube extending from within the conduit end fitting abutment and having a longitudinal bore into which the core wire extends toward the core wire length adjuster:
• and wherein a core wire travels less than 1.3 mm for core wires under 850 mm in length, less than 2.0 mm for core wires of from 850 to 1200 mm in length, less than 2.5 mm for core wires from 1200-2400 mm in length following 200,000 cycles of movement of the shift assembly, and wherein the connector pin socket portion when attached and removed to a connector pin requires an installation force of a maximum of 130 N and an extraction force of a minimum of 82 N following 200,000 cycles of movement of the shift assembly and the core wire maintains a length after application of a compressive load of 667 N five times for a duration of 10 seconds followed by application of a compressive load of 333.8 N five times for a duration of 10 seconds.
