Late Downshifts

My car has been downshifting to 1st late. Itll do it when i start to accelerate and its a really rough shift. It feels terrible. Every time it happens it makes me want to cringe. It used to happen every once in a while but now it is happening every time i drive the car. I knew my tranny was going to need to be replaced soon just because i have had some random issues that point to the tranny, but this worries me that i might need one very soon. Can anybody verify this, tell me what is going on, or even tell me that it might not be the tranny maybe the computer? lol i would love to hear that i wouldnt need to get a new tranny right now
 


say I slightly roll a stop sign going a couple mph, when I start to accelerate the car downshifts into first then. and because I'm already accelerating the shift is very harsh. it does feel like the car jumps. I had my dad drive it too and he is saying the same thing I am, very late downshifts to 1st
 
AZ scanner picked up a trans code in my 98 regal. if it comes back clean, it may need to happen a few more time to set a code.

or ask a trans shop to scan it, they will charge you im sure, but they can drive it and read all sorts of stuff going on inside, and pin point the problem.

have you serviced the trans at all? could be a clogged filter.
 




Clogged cat?? Mine had the same issue and I resolved it with a new cat converter.

my exact symptoms were as follows. Driving along, start pressing down accelerator, no shift, keep pressing, no downshift, keep going, retarded hard down shift to first with no pull
 
I've had the MAF for a little over a month now I don't see how it would take that long to settle in. and really a clogged cat caused that? I don't quite understand that but that sounds a lot like my symptoms.

Very common problem that imitates transmission issues. To be sure, go get the tranny scanned etc, if you already did or if it throws no codes, go ahead and cut the cat off and see what it looks like. Mine failed at 90,000miles. Got a new one, car drove better than ever.
 
if it was a clogged cat though wouldn't the bogging occur all the time? the bogging is intermittent not consistent at all

No, it would only eff up when you're trying to push more air through it than it can filter at a time due to it being clogged. It may be worth to look into as I suspect your tranny to be fine. As long as your tranny filter and fluid have been changed, it shouldn't be a problem, my money is on the cat. How does the car react when you floor it from 2nd to make it go into 1st, stupidly aggressive downshift that takes you nowhere?
 
I think it's fine. I've noticed it when I'm rolling stop signs. sometimes it bogs even when flooring it from a stop but the bogging isnt consistent that's wut makes me think it might not be the cat.
 
Didn't get all the way through the post, did see something about a new maf etc and someone suggesting that as a possible area.

New maf's are not always good. Often they can cause further issues. Trouble shifting etc are commonly caused by a bad maf or tps reading. Which might not set a code.
 
I have a 1 year warranty that will completely replace the MAF would u suggest going back to the dealer and saying the MAF is bad?
