What do the headlight and dimmer switch connect toon an 86 cutlass?

headlight dimmer is either on the floor left of the brake pedal or a function on the turn signal arm by moving forward 2 times per cycle click up on- click up off.. the actual switch is on top of the steering column just under the dashboard which requires the mounting bracket to be removed and the column lowered for acesss it is usually close to and just beside the actual ignition switch which is much larger in size..good luck..

My 86 olds cutlass has been sitting up for over a year, now i got it back on the road it won't get out of first gear. What can i do or check. HELP i love my olds.

Change trans fluid and filter. Sounds like valve body in trans is sticking. You might have to do this more than once to "un-gum"

Oldsmobile cutlass 1998 transmission dipstick, where is it? I can't seem to find it and an auto parts place worker couldn't find it either.

there is not a dipstick for a tranny. your car has a big red cap on top of the tranny, under the battery area
with engine running and cap off......if you can see tranny fluid, then you are fine.

What size engine and transmission do i need for 24inch rims?

best bang for your buck 350 cid with a turbo 350 or 700r4 ... the 350 engine can be stroked out to 383 using the internals:pistons and crank from a 400 in big block... but just stroking a 350 on a hot tranny with low gears to drive those big wheels is important get a 4;11 low gear ratio you ll be able to drag that monster.

I don't know the size of the original Transmition,that came in my Cutlass supreme 1987.,i jst put a 350 rocket in the car and need a tranny,the bolt patterns,weather or not the tranny has...

If I remember correctly that engine used a 350 trans. You will need to check bolt patterns on bellhousing to make sure there are no differences in bolt pattern but I believe they are the same. With a little work you could also stuff a 400 or a 700r4 (with overdrive) unit in there but you would need some mods to do that. Don't forget that tailshaft lengths vary depending upon where the unit came from so you may need to either change tailshaft or have a driveshaft made to fit.
