Most recently, automakers have focused on simplifying car maintenance in hopes of making life easier for their consumers. Car manufacturers have attempted to create “lifetime” parts, including sealed transmissions. What does this mean for maintaining your car? We asked a Master Mechanic what you need to know.
Why Do We Replace Transmission Fluid?
While you drive, friction materials from your transmissions clutches and bands will make their way into your transmission fluid. Traditionally, auto manufacturers suggested having the transmission fluid changed every 60,000 to 90,000 km. Modern cars, however, have extended service intervals for many reasons. They include:

Sealed Transmission Service
- Reducing the amount of “used” transmission fluid in landfills
- Increase maintenance intervals which reduce overall costs
Jul 27, 2019 Car makers eliminate the transmission dipstick many years ago. These newer transmissions are referred to as “sealed transmissions.” They’re not really sealed, but the design makes it much harder for the average DIYer to check transmission fluid level on a sealed transmission. But it can be done. Other than that, these so-called ‘sealed’ units are all quite serviceable with the traditional removal of the sump and the replacement of the oil filter, pan gasket and oil. I do however recommend that you engage a transmission shop to do the servicing required so all necessary inspections and adjustments are made and quality parts are used. Sealed Transmission is Complex You cannot open a sealed transmission to check or replace the fluid. Only the professionals with exact knowledge of the same can perform such applications. One should not even attempt to open or check the transmission oil by own. Methinks you are not as wise as you imply or have not thought out why the transmission is sealed. A 'lifetime' fluid is contained within a sealed environment and is not at all susceptible to the pollution or dirt as the old systems thereby lasting indefinitely, unless internal failure occurs.
How Do We Replace Sealed Transmission Fluid?
First off, you’ll know you have a sealed transmission if you don’t have a dipstick to check the fluid. That said, even a sealed transmission needs to have its fluid checked or replaced on occasion. Although this may seem to contradict the name, not having clean transmission fluid can lead to significant expenses down the road.
A sealed transmission doesn’t mean an inaccessible transmission. Your local Master Mechanic can check the fluid of a sealed transmission, however, the vehicle will likely need to be lifted off the ground to do so.
Can You Check the Transmission Fluid Yourself?
Even for seasoned DIY car owners, replacing the transmission fluid in a sealed transmission is not something you want to attempt. A minor mistake could lead to major costs, or worse, permanent damage to your vehicle. You may also risk voiding any warranty you have by attempting to service the transmission yourself. Either way, it’s best to contact your local Master Mechanic if you suspect something is up with your sealed transmission.
Signs Your Sealed Transmission Fluid Needs Attention
If your transmission is suffering from poor fluid quality, you’ll typically notice one of the following symptoms:
- A grinding sound when driving or switching gears.
- A delay when shifting
Since many drivers are holding on to cars for longer, the aftermarket is poised to service these vehicles and keep them ‘on the road’ for as long as possible. Automakers are aware of this and there is pressure on them to produce longer-lasting vehicles. There are other sealed components on your vehicle and we wouldn’t be surprised to see the number increase.
For now, it’s essential for you to understand what a sealed transmission is and how to recognize if there is an issue with yours. Remember anything in a vehicle can break down, even if the automakers claims it’s a “lifetime part”.

Double sealed transmission ball bearings are available for use in both three speed car and four speed truck transmissions. There have been a lot of discussions about sealed bearings for this application and many people are apprehensive or skeptical, but I believe sealed ball bearings are the best choice.
Consider several facts:
How many good used ball bearings have you ever found when rebuilding a Model A transmission?
Modern elastomer rubber sealed ball bearings are lubricated for life and are used in many demanding long life applications like prop shaft bearings and alternator bearings where they never receive additional lubrication.
Model A's have straight cut gears and generate a considerable amount of metal debris in the oil from shifting and gear grinding. This debris is circulated and is very abusive on bearings and shafts. Just look at any transmission and examine the countershaft, the wear and looseness of the ball bearings, and what comes out the drain plug. Model B's have a somewhat better condition, having helical cut gears except for first and reverse.
Worn and loose ball bearings typically found in Model A transmissions are the cause of uneven tooth wear and are a contributor to the cause of the shift lever trying to jump out of gear in 2nd and 3rd. This is due to the cam angle forces on the engaged teeth due to wear and misalignment of the shaft and bearings. This condition is especially noticeable with straight cut gears compared to helical ones.
Model A transmissions are also poorly sealed by the slinger and leak oil primarily out the back and into the universal joint housing. Oil can then find an even easier leak path, as well as lowering the oil level in the transmission.
By using double sealed ball bearings, the universal joint grease is kept in its housing where it belongs, the transmission oil is kept in the case where it belongs, and the bearings are run in clean grease without metal debris.
In the worst case scenario, the sealed bearing would develop a leak and would allow transmission oil or universal joint grease into the bearing.
In the worst case scenario, the sealed bearing would develop a leak and would allow transmission oil or universal joint grease into the bearing.

Sealed Transmission Myths
The part numbers I've used for the Model A and B bearings are Torrington-Fafnir 208PP and Torrington-Fafnir 306PP. These are both double sealed ball bearings of the correct size. The 200 series is the front and the 300 series is the rear.
The part numbers I've used for the Model AA and BB truck bearings are Torrington-Fafnir 209PP and Torrington-Fafnir 307PP. These are both double sealed ball bearings of the correct size. The 200 series is the front and the 300 series is the rear.

The PP suffix on the bearing is important. It indicates a double elastomer/rubber sealed bearing. Bearings are also available with metal shields instead of seals, or with neither seals nor shields as original.
Additionally, bearings are also available with only one side sealed or shielded. The bearing series number is a standard, but each manufacturer uses somewhat different suffixes to identify seal configurations, so ask your bearing supplier.
Pictured above are the typical double elastomer/rubber sealed bearings used in Model A and B transmissions. Truck four speed transmission bearings are similar, but are larger sizes.
Some people have expressed concern that the sealed bearings may have inadequate quantity of grease when new, based on their experiences with different brands. If that is a concern it is possible to pop the seal out on one side using a small jewelers type screwdriver and then add more new clean grease. Then snap the seal back in and assemble to the shaft.
If you are still a skeptic, consider using a rear bearing with only one side sealed. Magento mamp 2.0. I would put the seal side on the transmission side so that the universal joint grease will reach the bearing. I believe this is better because the universal joint grease is relatively clean compared to the transmission oil which is full of metal particles from worn gears.
