Needed some tips. Its a 97 aurora autobahn. 207,252miles I plan on changing trans filter and fluid since it smells burnt and prob never been changed. Planned on buying filter kit and high mileage fluid. And adding a sseafoam trans cleaner. But was told if I change filter it usually causes more problems.  What do yall think? My dad also told me I should just take it to a shop that just "reverse flush" he said I use same filter that they just flush the fluid out backwards so it cleans the filter. Any clue on that? I never heard of it. only prob I have with tranny is when its cold even after letti g it idle 20min is has shifting problems until fluid watms up. Figured it was bad fluid. Other than that shifts smooth. Just not sure if power steering pump has constant whine or if its the tranny. Kinda gets louder the faster I go. Kinda leaning towards tranny and my dad thinks ps pump |

I wouldn't flush it, just my preference.
Don't forget the magnet!

No flushing. Just change the filters & fluid.

With that mileage I wouldn't flush either.
Years ago I had a full flush/fill done on a Pontiac 6000 - similar mileage as your car. After the flush the trans shifted smoother for awhile (it had not been having issues previously), but less than 10K later it started to act up. The fluid was DARK, way darker than it was before. Long story short, I traded the car around that time but I figure the combo of power flush + new fluid really stirred things up inside and ended up not doing any favors.
New fluid could help with shifting in cold weather, esp. Dexron VI. Better in the cold in my experience. I run it in my 'rora.

If you do not know the last time it has been flushed do not let it get power flushed with that kind of miles on it. I used to flush transmissions, and although it is rare, there is a possibility that flushing can dislodge old dirty fluid and cause problems. If you drop the pan and just change the fluid that comes out when you drop the pan, replace the filter that would be fine. Because your just adding a few quarts to a transmission that holds fluid in every nook and cranny including the few quarts inside the torque converter and valve body. I would also recommend a quart of Lucas Oil transmission fix. That stuff works wonders. Its the only brand of additives i use on anything in my cars. Lucas Oil and royal purple are owned by the same company. Great products.. Good Luck

IMO I would flush it, I flush mine, these transmissions are bullet proof. If you are having problems before, a flush will not help, but will usually hurt but whatever was going to happen is anyway. The bottom filter is not really a filter, it's just a screen, the real filter is in the side cover of the trans, you have to lower the sub-frame to change it.
I don't think Lucas and Royal Purple are owned by the same person, but I could be wrong. The guy that invented Lucas oil treatments lives pretty close to me, has a huge farm with lots of land. They also have a racetrack out in the middle of nowhere, it is a very large dirt track.
I have extra transmissions if anyone does have problems, I can ship and would sell them cheap to get them out of my way, these heavy beasts are not easy to deal with.

I read that the final drive is slightly different. So seems just filter and fluid, no flush. Any thoughts on the seafoam transmission cleaner stuff? Ive used the formula for my engine and gas in my turbo 4 banger with no problems, but never tranny |

Randy, would you suggest I change the actual filter too? I dont care to do the work, I just hear alot that people see more problems after touching the filter. Im not a tranny guy, usually I have a problem with one, I just get another lol.

Pretty much impossible to change the side filter without removing the trans.

I think I read it on here a long time ago, you can take the bolts out of the drivers side subframe and loosen the passenger side to get enough clearance to remove and install the side cover and filter. I have done it on a 4t65e to change some solenoids. On a related side note subframe bolts trap water and rot over time, they all need to be checked. I would plan a Saturday, remove intake and coolant crossover gaskets, while apart lower subframe and change transmission side cover gasket, check all sub frame mounts and bolts, reinstall coolant crossover and intake. It is nothing to drop the whole powertrain on these, 2 hours at the most, with all the wrong tools. Trans pan drop |

The company Lucas oil comes from the Lucas gusher in Beaumont TX, still called spindeltop, even have a museum for it. both are made in plants north of Houston. A Lawyer friend of mine was telling me how his grandfather knew the Owners. Facinated me cause I have been using royal purple since 2001. That's when he started telling me the history of how royal purple came to be. I guess some stuff just cannot be googled. I'm going to take your word on the toughness of the trannys, gonna go get mine flushed.. Corrections. Not sure where my friend got his info but Forrest Lucas is from and lives in California.. hummm. Not sure why I never Googled it.. But purple is made in north Houston. Lol |

I dunno about these power flushes. The regular pan drop and fluid change can only help though.

You don't have to take my word for it, check out 99 Cadillac Death by Boot, the engine does pretty well, starts going bad about 6:45. From what I read on Forrest Lucas, he is a resident of Indiana and has a cattle ranch in Missouri. It also said he has a racetrack in California, so it would make sense if he has a house there, too. I have a lot of friends that work for them and have been to the track in Wheatland many times, it's pretty nice. A couple years ago a guy working for Lucas was taking a girl for a ride in a company helicopter, the clipped some power lines out and both were killed. They were both local people and it was a pretty bad deal. Protect the Harvest: Forrest Lucas |

I took one with 170,xxx miles to get a flush and pan drop services. It was at a Cadillac dealer though and I wasn't having problems either. They put dexron 6 in and it was even better after that.

Yes, DEXVI. Walmart is the least expensive for the same stuff. Throw some in your PS system too.

4T80E - Best 'Wrong wheel drive" tranny GM ever made. Never let your ATF fluid "turn" (burn, oxidise, cook, smell...) it looses the friction modifiers and will self perpetuate more damage; generate more heat and get thicker and smellier quickly. Old transmissions can have a fluid flush, if is filtered and uses genuine ATF, but avoid solvents. Yes, get name brand Dexron VI for your unit.

Wow, I guess we learn something new everyday. Looks like I'm going to get mine flushed really soon. The not so intelligent person that put my engine in my car used regular cheap dexmerc. Looks like im gonna spend some money on that now.

It is listed under 're-branders'.
Use with confidence.
