If you've ruled out that it's the rear tires chirping, then it's most likely belt slippage. This is common on the Corvette LT1s and even some of the later L98 motors. On hard shifts (auto and manual transmissions), the shift in the speed of the pulleys will throw the belt and hence the screech of it slipping. It's pretty harmless, although it can be annoying.

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

Maintenance! Check the fluid level periodically, repair any leaks/problems promptly, service the unit on a regular basis, and add an auxiliary cooler if the vehicle is used for towing, commercial, or high ambient temperature climates. Synthetic fluid may benefit some applications by lowering operating temperature resulting in a longer life, but not all transmissions can use synthetic fluid. Check with your local ATRA shop for their advice to your specific application and needs. See similar questions...

Yes. While not every category is available in both automatic and manual variants, we do have a varied selection of automatic options to choose from. See similar questions...

Yes, you can but it is best that you keep the shot relatively low (no more than 75). For smaller shots the automatic guys can actually sometimes get a better benefit out of nitrous than manual guys because you do not have to get off the gas to shift. The problem is that over time the bands in the auto tranny will eventually wear out. See similar questions...

With some automatic overdrive transmissions, towing can result in excessive shifting of your transmission between overdrive and the next lower gear -- this is especially true if you are traveling in mountainous areas with a heavy trailer. If excessive shifting occurs, it is recommended that you lock out the overdrive gear to eliminate the condition and provide steadier performance (refer to your vehicle owner's guide for specific information).

All Hummers have automatic transmissions, even the military ones. It was one of the U.S. military requirements, that it be easy to drive. See similar questions...

This is a common problem among 6-speed cars. GM is aware of the problem. The faint but distinct rattling noise can usually be heard with the transmission in neutral and the clutch out. A few quick revs at about 1/8 throttle and it should get louder for a fraction of a second, then disappear, and then return when the engine drops back to idle. You should also be able to hear it when starting out in first from 0-10 mph. See similar questions...

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...

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.

This is completely normal. On cold mornings, both of my 91's will delay going into overdrive until somewhat warmed up. I think the delay has lasted as long as 8 - 10 minutes. See similar questions...

Answer: Some articles have mentioned at some time an automatic transmission will be available, but not at the beginning. General estimate is either available half-way through the Solstice first year of production, or sometime during the second year of production. There has been no official mention of the timing for an automatic transmission. 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...

There is no accurate answer. The mileage or time of use before major problems occur will vary greatly, and therefore, I don't dare suggest a specific expectation. It is true that most modern transmissions, barring damage from poor maintenance, overheating, or other abuse, tend to work properly for something more than 100,000 miles. The three major factors in transmission life expectancy are periodic maintenance, maintaining proper fluid level, and moderate driving habits. 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...

Yes, a seat is required for the examiner. The seat must be safely bolted to the interior floor of the cab. A seat belt is required for both the examiner and the applicant. See similar questions...

Horsepower increases of more than 60 hp may require transmission modifications. Dodge trucks equipped with an automatic transmission should have the BD performance torque converter and valve body installed in the transmission. The torque converter should be matched to the horsepower of your engine. Increasing the horsepower of the engine will increase the slippage of your torque converter. See similar questions...

On cars with automatic transmissions and the 2.73 rear (GU2) 1st gear can't be selected because in order to pass the Federal noise pollution tests, GM had to lock out selectable 1st gear. It has to do with downshifting into the lowest selectable gear at some speed as the car goes through the sound traps. With the 3.23 rear end, the required speed is high enough that the transmission won't allow a manual downshift all the way to 1st gear. But with the 2. See similar questions...
