Transmission fluids licensed by General Motors to use the trademark DEXRON III are required in the Allison 1000 Series™ transmission.

Different transmissions require different types of transmission fluid. The experts at BEAR recommend that you change your fluid every 25,000 to 35,000 miles as a part of our regular suggested maintenance --Safeguard Service. This service also includes replacing the filter or cleaning the screen, replacing the pan gasket, performing a final leak-check, and performing a road test. This service is warranted for 90 days against any leaks from your pan gasket. See similar questions...

TranSynd is a fully synthetic transmission fluid available from Allison Distributors/Dealers or at GM dealers. TranSynd is a licensed DEXRON III product and has been extensively tested by Allison Engineering in a broad range of Allison products. While TranSynd was developed mainly to meet the harsh operating conditions of heavy-duty transmissions in severe operating conditions like transit buses, its benefits translate to the pickup truck market.

Any fluid that meets DEXRON III requirements is suitable for use in the Allison 1000 Series™. Always verify that the container reads DEXRON III, regardless of whether it is mineral-based or synthetic. See similar questions...

The TR-3550 5sp uses the GM Synchromesh. The T56 and 3650 use Dexron III ATF, and the Viper T56 should use Castrol Syntorque. See the service manual for more details about your transmission. See similar questions...

always, if your car is under warranty, we suggest following your manufacturer's recommendations. In most passenger cars we recommend using Royal Purple Max Gear 75W90. Some people may want to use something lighter, in which case, our ATF or Racing 41 would be good suggestions. Racers may even want to run the Racing 21 which is fine. Many new cars now use an ATF or engine oil. See similar questions...

You should use only Tempest “Rosco” smoke fluid in Tempest “Rosco” Smoke Machines. The earlier Tempest smoke machines (1601, 1801, 9000) were manufactured by Martin and use a Martin specified formula. Tempest offers a “generic” smoke fluid that is safe to use in other brands of machines including the Martin machines. See similar questions...

The human body needs water to replenish the blood and fluids in order to work properly. Water regulates the body's temperature through perspiration, removes waste via urine and carries nutrients and other substances throughout the body. It has been recommended and promoted in the media that we all need to drink around 6-8 glasses of water each day, however there is no evidence to support this. The best way of knowing how much to drink is to drink enough to satisfy your thirst. See similar questions...

Use ONLY what it says in your owner's manual to use. Many Chrysler transmissions are NOT compatible with standard fluid! ATF+4 is usually the best one to use with automatic transmissions before 2001, ATF+5 after. THIS IS AN IMPORTANT and very misunderstood issue. Please see the discussion at the end of this part of the FAQ. See similar questions...

Each engine manufacturer has different specifications. Please check your owner's manual or call the engine manufacturers tech support number. See similar questions...

Use only DOT 3 or DOT 4 brake fluid. The use of any other type of fluid will damage your brake, and could cause your brake to fail. We recommend using DOT 4 brake fluid because it has a higher boiling point than the DOT 3 brake fluid. See similar questions...

A:If you use a transverse engined car at a track for speed events (as opposed to a parking lot autocross), you may actually be in a corner long enough to slosh oil clean away from the pickup, with possible bad results (please don't ask how I know). The real solution is to get a baffled oil pan, but synthetic oils will do better than dino oils in this situation. far as I know, most/all water cooled VW transmissions require gear fluid with an API rating of GL-4 (MIL-2105). See similar questions...

We use glycerin, FDA approved. This food additive is found in many recipes, the most common being frosting (or icing) on cakes. It is also used in some skin creams, makeup and lipstick. Others use animal-based Glycerin or water combinations. See similar questions...

Check fluid level with the engine running (except Honda), the transmission in "Park" (except Chrysler products which should be in neutral with the emergency brake applied), and with the engine at operating temperature. Remove the dipstick and wipe clean. Fully insert the stick and remove. Check both sides of the stick to determine correct reading. Repeat the process. The reason you have to check both sides of the dipstick is that circulating fluid can have surface waves. See similar questions...

Changing your transmission fluid regularly will extend the life of your transmission. On most transmissions, there is also a filter that needs to be changed at the same time. Most transmission specialists suggest changing the filter and fluid every 30,000 miles, even if the fluid looks clean. What happens is over time, it breaks down and becomes dirty. The operating temperatures will rise and lubrication will decrease, leading to premature wear and transmission failure. See similar questions...

Like an automatic transmission, the fluid in your manual transmission needs to be changed regularly. Changing the fluid will extend its life by removing dirt and moisture and by maintaining lubrication and minimizing high speed foaming. When the fluid gets dirty, it can no longer lubricate as it was designed. See similar questions...

Tufoil is too slippery to use in automatic transmissions. The oils in them need to be a bit grabby or the clutches won't work properly. In manual transmissions, about one part Tufoil in ten parts high-grade transmission oil will make them run cooler and shift smoother. See similar questions...

We would strongly recommend that you do not use any of the available products that are sold as additives to stop a leak from the system they work by swelling up all of the rubber in the entire system and can in the long run cause more damage than the original leak. No the rubber bellows are designed to keep dirt and debris out of your steering rack and not to keep fluid in. The rack bellows should only have a small amount of grease inside them.

Yes, Bar's Leaks is one of the only transmission stop leaks that is compatible with all petroleum-based transmission fluids including synthetics. See similar questions...

It is better to change the oil and transmission fluid at the end of the season, prior to storage. Lubricants naturally accumulate moisture, combustion by-products, and other contaminants during use. It can be detrimental to store an engine or drive with large amounts of these contaminants present. See similar questions...
