Common Problems with the Mercury Marauder Transmission

TCC Application in 2nd Gear – 4R75E Transmission / 4R70 Transmission

Problem – A lack of power after the 1-2 shift can be caused by an un-commanded torque converter clutch application / TCC apply. The P0742 and/or P1742 DTCs may also be stored.
Solution – The #7 check ball inside of the valve body may have worn down to an incorrect size, allowing the torque converter clutch to apply after the 1-2 shift. Replacement of this check ball may solve the problem.

Slipping in All Forward Gears – 4R75E Transmission

Problem – Many Ford vehicles equipped with the 4R75E transmission, may experience excessive slipping in all forward gears. Metal shavings may also be present in the transmission fluid.
Solution – Replace forward clutch drum and update ECU with program 06B06

Mercury Marauder 3rd gear slipping

This is perhaps one of the most iconic FoMoCo limited edition vehicles in the modern era. But Mercury Marauder 3rd gear slipping can put a serious damper on the fun factor. When it happens, the 4R70W/4R70E or 4R75E transmission will shift into neutral during the 3-4 shift. You may also notice a lack of engine braking if you manually shift it down into 2nd.

Cause of the Mercury Marauder 3rd gear slip

These Mercury Marauder 3rd gear shift problems are typically caused by a broken overdrive servo ‘E’ clip or overdrive servo retaining snap ring. Should this be the cause, the debris from those broken pieces will work their way into the overdrive servo regulator valve and prevent the overdrive band from fully applying. If you decide to just have your transmission rebuilt, the mechanic will need to completely remove the overdrive servo regulator valve assembly from the valve body and repair the damage caused by that debris. This step is often skipped by most transmission rebuilders. However if you step up to a reman Mercury Marauder transmission from Street Smart Transmission, you can rest assured that that step will be overlooked.

How much is it going to cost to fix my 4R70W/4R70E or 4R75E transmission?

Unfortunately, the problem described here will require the removal and disassembly/partial disassembly of your transmission. Given the labor time involved to remove the transmission from the vehicle (this is not a simple task), most repair shops will recommend that you go ahead and rebuild the entire transmission while it’s out. Since they already have to tear it down to replace the 4R70W/4R70E or 4R75E transmission, it sort of makes sense to spend the extra money to do that. After all, you should get a lot more mileage out of your transmission once it’s rebuilt. And since they’ve already got the transmission apart, might as well, right?

Can I drive with a transmission problem?

If your Mercury Marauder 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 Mercury Marauder transmission need to be replaced?

The overall lifespan of a Mercury Marauder 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 Mercury Marauder 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 Mercury Marauder transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Mercury Marauder 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 Mercury Marauder transmission replaced?

In order to replace your Mercury Marauder 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 Mercury Marauder Transmission Problems

Solution A: Buy a Used Mercury Marauder 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 Mercury Marauder 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 Mercury Marauder 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.

Hi ive got a 2004 marauder and when i put it in drive and start going it shifts all the gears with noproblem after the final drive gear it all of a sudden starts to coast it has no drive gear but if i shift down to second it goes back into gear and then shift back to drive it will continue going and then slip right back to coasting again im not sure but it might be a solenoid or front pump. The transmission doesn’t slip it just feels like it just lost pressure and wont stay going

Would love your thoughts, please comment.x
