1996 Buick park ave ultra starting to slip

[Angelo Jr]

Hey everyone I am new here, my Buick has recently starting to slip, it started probly a little over a month ago and now it's having problems going from 1st to 2nd, when I first got it I would accelerate just up to 10-15 mph, release gas, then quickly gas it again and it would catch gears, but now it won't even let me do that it's like the car doesent wanna go faster than 30mph, and I can't drive on freeways or long strip street areas, but if I'm at a stop light or sign, or a area that requires a lot of turns and stops its ok, I'm just totaly confused! I don't know that much about cars so excuse me if my explanation sounds strange, but what would I need to do to fix my tranny from slipping anymore? I researched online about the problems but couldnt get a appropriate answer, and I don't wana get ripped off by the mechanics either....


So please anyone who can relate what should I do?

I was thinking about gettng the tranny drained, new pan and filters cause there is metal shavings in the pan so I know that can't be good, So Should I go with that? Also I've been running it without the supercharger belt can that be another reason?

Also I heard of this Lucas tranny fix stuff will that work?

My car is around 350k on it, so it's one for a new oil change as well

Any help on resolving my problem would be greatly appreciated, thanks again guys!

Sorry, but a 1998 will not work in a 1996. The 1996 still had a modulator valve, whereas the 1998 is fully electronic and uses shift solenoids.

If that transmission lasted for 350K miles, it's amazing to me !! Hope you can figure out a fix for it.

Overhaul/rebuild time....research & select carefully if shopping for a rebuilt unit. Field repairs (i.e., local rebuilders) are not as easy on these as they once were on the older style transmissions. Factory upgrades are put into production quite often on most models, the most reliable remans come from GM. Cost is higher than the local trans shop, but the warranty and reliability is better.

What ever you decide to do, perform a very, VERY detailed and careful flush of the cooler and external components prior to installing the unit.

Don't flush your tranny. Just don't. Check ur vac lines and use some Lucas... And pray.
