Sounds like it was going out before but fixed it self so you might need to go to the shop and have the trans flushed

SOURCE: 97 gmc pickup with automatic transmission trouble

1st thing to do is test the system for codes, the problem is most likely a failed or stuck shift solenoid indside the trans, have you ever serviced the trans, sometimes a fluid and filter cahnge will cure these kinds of issues.

Reverse is not sycronized, this means the gears have to stop to mess and not grind, two thing cause this, being to quick to slam into reverse after clutch is depressed, a problem with the clutch.

my friend you are having valve body problems, the 1-2 shift acumulator valve is probably stuck, you have to service the valve body or replace it

GMC Sonoma automatic Transmission Problems, engine rev's in D & 3rd


First check trans. fluid. It should be full, & clean. Clean means light red color fluid (like red cool-aid) if it looks like darker red, or brown fluid, like motor oil, that is way too dirty & should be flushed. May need to change the filter too. dirty trans. fluid is your big enemy. could also be an electrical problem in the trans like a shift solenoid or something like that, but check for clean fluid first.

97 Honda Odyssey Auto transmission downshifts


Try checking your timing to solve the ping problem, your timing might be too far advanced. For the downshifting problem, I have this same issue on my odyssey, On the top of your efi manifold you will see 2 wires that control your throttle, One of them extends to the transmission and basically lets it know when you are pressing firmly on your gas pedal, telling it to downshift. I would adjust it so the cable has some more slack in it, therefore requiring a harder press on the pedal before downshift, and hopefully a sooner upshift. You can also slightly adjust idling problems if the van is running high while in park or drive while sitting. As for the gas vapor purge code, I would first try replacing the egr valve, its only a couple bucks and takes no more than 5 minutes.

Grinding gears from 1st to 2nd, 3rd to 5 ok


Either your clutch is getting bad, or you're shifting down too soon, and up too late. Try double clutching. Push in your clutch and push it into neutral. Release the clutch, fan the gas pedal, push the clutch again and shift into 1st. All this does is sychronize the speed of the transmission with the speed of the engine. There were, in the 60's, a lot of cars with the old "three on the tree" that you had to do this every time, and you get pretty good at it after a while.

2001 sonoma parking brake petal wont lock into place


There's a ratchet in the top of the pedal which holds the pedal down when depressed. This ratchet is worn, broken, loose, or it just needs lubricating. I would first try WD-40 on the top of the pedal where it attaches to the frame/chassis.
