Signs of a transmission problem

Whenever you observe vibrations when your drive, your automobile’s transmission could be giving out and you had better take it to Harolds Sons immediately. If you hear a scraping, grinding or rumbling noise from the automobile whenever you start to go forward or in reverse signals an automatic transmission problem. The transmission fluid might be low or the fluid could be dirty and requires changing. Even if you do not observe anything more than one tiny symptom, you had better still have your transmission checked HAROLDS SONS TRANSMISSION’S will be happy to give you a professional opinion about your problem at no charge.

Whenever you start the automobile and move the gear shift to drive the automobile and nothing happens, the shifter’s linkage may be broken. If you don’t feel the engagement of the automatic transmission, there are probably internal transmission problems. This specific trouble might take place abruptly without any prior warning.

All strange grinding or whizzing sounds when the automobile is in gear should be checked out by a qualified transmission shop such as HAROLDS SONSTRANSMISSIONS.

    Sealed transmissions are quite possibly the dumbest design on vehicles.

    Damn. I wish I had my standard again. I drove a Toyota truck 240,000 miles with no transmission problems, but it was a standard. I let some people talk me into buying a car with an automatic, already broke!

    2005 GMC Sierra 4×4,140K miles, 5.3L, 4L60E Transmission – Intermittent P0894 DTC after long (~1 hour) drives, especially in summer. Maybe once a month at most.

    I understand that the code can be set due to 3 separate actual physical problems according to dealer notices I’ve come across. But I’m not convinced there’s an actual slippage occurring. I’ve seen zero metal shards in transmission fluid, at least from examining dipstick, there is no burned odor, and fluid has normal viscosity and color.

    Only issue I experience is after code is tripped, PCM sets a pressure value in transmission to max, as a safety measure, and it causes hard shifts, especially in lower gears.

    My process is to just reset code with code reader, and transmission again performs normally, just as it did before DTC was tripped, since pressure is back to being modulated correctly by PCM.

    Is there an easy diagnostic test to tell if the transmission is actually experiencing slippage, or if it’s just a sensor issue due to heat?

    If it’s just a sensor issue is just continuing to clear the code sustainable?

    Thx in advance – Also – Great videos.

    I have a 2010 Chevy Equinox that is seeping transmission fluid around the pan gasket. What is a typical quote/cost for this repair?

    Do you guys touch sealed transmissions? I have a 2003 Jaguar x type and it’s got a few problems. One I need transmission flushed and filled. Also been having a problem with the alternator not charging the battery. And no can seem to figure out what the issue is.

  9. Phoenix Transmission, says:

    I have lived in Laveen, Arizona for the past 50 years. In fact, so my children went to school with some of the Smalley family members. Three generations of my family only trust Harold’s transmissions to fix anything on our cars. They are Christians and used to go to the same Assembly of God Church as me where Harold’s brother Pastor Cliff Smalley preached. I highly recommend if anyone in Laveen or South Phoenix is having problems with their car’s transmission that they take it to Harold’s Sons on Broadway Road

    My truck slipped a couple of times I changed fluid and filter and a week later I did it again. It never slipped again. Got another 50k miles before I traded it off

  11. Chris says:

    Burnt transmission fluid may also smell burnt, as my GM transmission using Dexron III did when it failed.

  12. Allison says:

    Manual Transmission = harder to operate, easier to understand
    Automatic Transmission = easier to operate can barely understand.

  13. Millie Hue says:

    Thanks for helping me understand that the transmission already has a problem if the gear is not engaging well once you turn on the engine. I guess I have to seek an expert already because this is what actually happened to me when I started the engine this evening. I was about to go out to buy from convenience store when I was not able to even get out of the garage because of this same issue.

  14. Millie Hue says:

    Thanks for pointing out that no matter how small the problem might be it would still be better to take the car to an auto repair shop to get it checked. I will follow your advice to keep it from getting worse. It just started having leaks this evening when I parked it in the garage and saw some drippings from the driveway to the garage.
