Can I drive with a transmission problem?
If your Lincoln Aviator can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.
How often does a Lincoln Aviator transmission need to be replaced?
The overall lifespan of a Lincoln Aviator transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Lincoln Aviator transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.
How are Lincoln Aviator transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Lincoln Aviator transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.
How is a Lincoln Aviator transmission replaced?
In order to replace your Lincoln Aviator transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, for the 6L80, the vehicle PCM will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

How to Solve Lincoln Aviator Transmission Problems
Solution A: Buy a Used Lincoln Aviator Transmission
The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.
Solution B: Buy a Rebuilt Lincoln Aviator Transmission
Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.
Solution C: Buy a Remanufactured Lincoln Aviator Transmission
Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

Have a problem of not changing gears!!
Check transmission light keeps coming on, overdrive light blinking, chugging, hard shifting…
2004 – Lincoln Aviator (LOW OIL PRESSURE) chimes on My Dashboard Every “Freaking” Day; if I’m not Malfunctioning on my Grammer as well. It’s Been Since (2016) When I first purchased the SUV… As I was pulling up to the Dealership from the test Drive. As I get Ready to Place the Vehicle in Parking Gear, Engine Excessively Reduces Power, Chime Bell Turns up in the Notification Panel Dashboard… Followed by Engine Completely Shutting Down, While still on 2nd.Gear Process? I would like to Apologize in Advance for my Language But… “WTF” is up with this consistent Issue? I know your probably thinking? Why did she still purchase the Vehicle Knowingly about the Problem issued? I must Say, that I truly believe that I did not make a bad Buy! I mean it’s obvious; Look How Far it has managed to pull on through? Furthermore, If I may add… About (2+ yrs.ago) I also took it to a Certified Auto Repair Shop to finally Fix this problem issue. We’ll that was the initial intent for the Repair I supposed! After Almost dropping ($4,000) on “Repair & Labor” cost’s… This problematic issue continues, it was not Fixed Replaced nor repaired! 👉 Bad News Travels a long way Sir, TALK TO ME?
The vehicle wont move in any gear R or D 1st 2nd 3rd 4th or 5th … it just limps about 2 or 3 inches and then nothing. Like a clutch is worn out type of feeling.
Check transmission light comes on overdrive light flashing and then it’ll go off and may not come back home for 5 minutes it may come back on 2 minutes later it may not come back on for 2 days no hard shifting no slipping just the light and yesterday the check Advtrac light came on as well but I killed it turned it back on and those that light went away. I’m also here in hissing sound from under the dash I’m not sure if it’s the brake booster or what but I don’t have an ABS light coming on. I have a 2005 Lincoln aviator two wheel drive.
My 2004 Lincoln aviator has the transmission light on in addition to display a check transmission message. It has lack of response, not running over 5 mph. There is a noise (like a bell) between the engine and the transmission. Mileage is 310,746. I need to get the code. It has a burning smell.
My 2004 Lincoln aviator goes fast going forward but l have no reverse , l change the solenoid and oil but nothing changed
I still don’t have reverse.
The light on the shifter blinks when I change gears.
Transmission light code p0741 tcc excess slip code on a 2004 lincoln aviator at 50 mph and sometimes dies when stoping at stop sign and or light. Had the Filter and fluid changed but it didn’t fix the problem what would be the next cheapest way to fix this issue
My 2003 Aviator “check trans” light came on as I noticed a slight slip between 2nd & 3rd.
I immediately changed the filter & fluid (fluid & pan were fairly clean), but did not fix. Got OBD code P0775 so I installed new shift solenoid block, but no change.
Doesn’t want go forward r reverse at all it feel that it’s going into shift but that move it try’s can it be a senor
I’ve got a 2004 Lincoln Aviator and my wife was driving it at the time I wasn’t in it when it happened but what she said if you’re familiar with the area she picked up our son up from school the other day and was coming up mountainburg hill and all of a sudden she had no gears what so ever I mean none not even reverse what could’ve happened all of the linkage is still connected I just don’t understand it transmissions don’t normally go completely out like this
