Wow, is the above post ever wrong! The cap IS reusable. There is a tiny slot to depress a plastic plunger which allows for the release of the latch holding the cap in place. This can be accomplished with a small pick tool.
~ Replaced the brake switch to try to solve the stuck in park issue,...no solve
~ Transmission fluid was OFF the Needswings dipstick...(Thanks Rob for the call on how to correctly use the stick)... Used the new Petrosin to bring it to the proper level.
~........actually we did this first before changing out the brake switch in the 92 degree direct Florida sun.
~ Connected battery and got a No Crank, No Start. Manually over-ride of shifter to crank in Neutral produced a no crank, no start...wiggled the shifter and it did start.
~ Shifted from reverse to neutral to drive several times to circulate the fluid....shifting is still HARD banging...dash shift indicator display is a solid block..
~ Folded passenger footwell carpet back to reveal the panel housing the TCM(?) and inspected all wiring for signs of tranny fluid wicking back or any squirrel damage...none found.
~ Did you remove the multi pin connector underneath and clean or replace it yet with a new one?...not yet..
It will probably need DRBiii reprogramming if the TCM has to be replaced , so I read. Theres one on ebay for 3400 bucks.
~ The BAS ESP light has not come back on, which is a good sign but it may be intermittent...speed sensor fault causing the shifter lockout perhaps?
~ The charging indicator ..the battery symbol...is lit...but the alternator is putting out...could it still be putting out even with bad diodes?
~ This car has apparently had several owners...I'll bet they've all had these issues which is why it was passed around like a ....well...like a ...
~ While replacing the brake switch we unplugged the seat relay and brightened up the contacts...Seat Works now...yaaay...
Oh Lord, We're Stuck in (PARK) Lodi Again...still !
