OK, GOT IT YES THE RANGE SELECTOR (THAT IS THE FORMAL NAME) SWITCH CAN CAUSE THIS ISSUE
Hello
The engine
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM and
TCM (Power Train Control Module, Transmission Control Module). When a
problem like this or other drive-ability related problems occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL
A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Hi emissionwiz, Relay I referred to is located underhood in the relay & fuse box. Relay is controlled by the neutral sw. & energizes the starter solenoid when neutral sw. is in P or N. Besides the "check engine" light, the starting problem is another one, possibly relating to the neutral sw, The neutral sw. has 6 terminals, 2 starting, 2 B/U, & 2 to let the TCM know what gear the trans is in. Possible the neutral sw, is causing both starting & trouble code problems ??
Thanks for your reply, Bill
WHAT ARE U REFERRING TO WHEN U SAY STARTING RELAY, WHAT WOULD THAT HAVE TO DO WITH TRANS ISSUE, PLEASE EXPLAIN
