View Full Version : shifting slowly/irregularly?

10-11-2008, 08:04 PM
So i got a 86 olds cutlass ciera brougham (V6, 2.8 multiport) and when i get to 20 mph the engine sounds softer and than when i get to 30 it kinda sounds up a bit again than a lil after 30 mph its silent, like it should be, well not EXACTLY silent but its how it should be, is it supposed to shift like that? that quick? i mean 20 mph and than 30 that seems... to close together to be shifting like that. And than at around 50-55 it gets a little louder to shift than it goes back to how it should be. Also, when im reversing/going backwards/ its pretty loud, but than when i put it in Drive/forward, it sounds to how it should be, quiet. Also this car has 140,900 miles on it. Just recently replaced some parts. (alternator, starter solenoid, battery, gas line, brake line). And the transmission fluid was DARK/pitch black, so i changed that not to long ago.

3 speed right? Shifting around 20 is about normal for 2nd, and 30 for 3rd is the same.

Does reverse whine? I think that's normal as well...depending on how fast you go.

50 comes around, and I bet you hear lockup engage (makes a distinct tone, at least for my car it does). Nothing to worry about.

The shifts are fine assuming your just applying normal throttle, noise in reverse is not normal for an automatic-but given the age I would probably ignore that unless there's a functional problem with it or it gets worse.

Yes im pretty sure its a 3 speed. Ok thanks guys, now im not so worried, you guys being pros and knowing what your talking about. (: nice cutlass tongle.

Thanks :) It'll be getting a new paintjob sometime in the next month or so

On a side note, be happy your car shifts so "late". Mine shifts from 1-2 at around 10-12 on a light throttle and it drives me insane! I'm in 3rd by 20mph. lol Reminds me of a shitty import except there's no more gears after 3rd >_>

Our Allison 6-speeds in our work trucks (International DuraStars) are in 5th gear by 28 MPH lol...

oh. lol. wow thats even earlier yet for a shifting i suppose. What color will you be changing your cutlass 2? Mine is a salmon color and i would like it to be black.

black and if it' snot too expensive, silver along the bottom.

nice. how much were the 15' rims? or were those on already when you bought it?

Err $150 for the whole set I believe...I can't remember exactly, got them off ebay. They came off an Alero.

oh nice, ive been thinkin of gettin bigger tires, right now i got 14 inch rims, 2 that are in the front are a wider and a little thicker rubber part, and the 2 in the back are 14 inch rim but the rubber part is not like the 1's in the front so their kinda... not matching... lol. so i need 2 replace the tires but i would like to get new rims at the same time, but my uncle says that bigger size rims might not work with what i got...=[

215/60/R15 is what I use, it's within .2% of the original tire circumference.

wowwww.... so thats cutting it pretty close huh? like if they were too big you could tell when the wheel turned right? cause it would probably rub against the top and sides.

I just ran across your post. I also have an 86, with 2.8 F.I. Transmission Fluid was almost black, shifting irregular. My car has only 41,000 miles on it and I was concerned. Learned that its critical to have the TV cable properly adjusted,(Carb linkage to trans, easy to see) or you can burn up your tranny very quickly. We also have Vaccum Modulators which control different aspects of shifting. Very easy to install, and very cheap to buy. Right on the front of the engine. Just though I'd comment.
