How do I change the battery in the speedo on the lotus Montana

This is a video for a 1999 Montana. It will be very similar to doing yours.



1999 Pontiac montana battery change

If the alarm was on, when the battery went flat - and I suppose it was - then you have to follow the manual to teach in your keys again.

Turn off the alarm and then remove the neg. wire from the battery before the alarm gets active again. Then remove the pos. wire and take out the batt. Insert the new battery in reverse order.

Well it would be the first time I ever heard of it happening that way. Have you recently changed size of tire and/or rim? that could very well affect your speedo.

Check you fuses, chances are the fuse has gone bad and will need to be replaced. You have a fuse panel under the hood by the battery and another fuse panel on the passenger side of the dash at the end, just pull the fuse panel off and you'll see the fuses.
Thank you for using fixya and keep us posted.

take it out for battery change-
put it back in to hold battery in place
if i am reading the question right

Does the black wire have any kind of special end on it like a plug ect. ?
Please let me know.

i have the same problem with me 2000 montana. i was told that it was the tcc switch. it means that the torque converter is stuck in the on postion. to fix the problem i was told either to swap out the tranny with another used one or to have the switch replaced. the switch is internal and they need to drop the trans down to access the panel on the front driver side. the part is only $90 but its 3 hours labour.

Have you checked the transmission fuse?

take to dealer have them do cluster sweep if fails replace some models are covered under campiagn recall check out at dealer to see if you qualify.
