Hard Shifting after highway driving (1997 Chevrolet Tahoe)?

Anyone have any thoughts on why my 1997 Tahoe shifts extremely hard after 10-15 mile drive at highway speeds. This shifting feels like the rearend is goning to come apart. This shifting can be easily fixed by just turning the truck off for 5-10 seconds. I have tried to resolve this problem with a new valve body in transmission made better ), and new solenoids ( no change). Any help would be appreciated, Randy Folkers I bought my truck used and noticed it shifted hard out of 1sr gear. I mean it feels like the u-joints are going to snap. The transmission finley went out. I had it repaired and it still shifts hard out of 1st gear.

    My 1997 chevy Tahoe does the same thing. After driving for a few miles on the highway my Tahoe will begin to shift very hard out of first gear. After shutting off for a few seconds the problem is fixed. One person told me that the engine has a small miss and the computer is making up for the miss by using the transmission. Therefore it causes it to shift harder. Don't know if thats right but would like anybodys ideas on this.Thanks,

The problem sounds like your kick down cable has gone bad. There should be a cable that runs from the transmission to the linkage on the TBI(i'm assuming it is a TBI[Throttle Body Injection]) At the throttle bracket, it is the lowest cable. It should have a little plastic box and you should be able to push on the button and slide the little plastic piece in or out of the box. This will adjust your shift points, being plastic, the cable likes to slip if it gets old. Also if you have book or have access to one it should tell you how to locate and check it but usually you have to replace them once they start to slip, the one I got for my 1992 was only like 28 dollars so it's not to bad just a real pain.

Usually bad "solenoid pack" inside automatic trans. Although, you usually also get a slight hesitation followed by a "clunk" when switching from forward to reverse. Also possibly computer programming error. If it has "adaptive" shifting (i.e. "computer learns your driving pattern and shifts accordingly"), you can have Ford change the programming to a standard shift pattern. (It's a wonderful difference in transmission performance).

If tranny is manual shift you may have a bearing and or bad gear. Try changing tranny fluid. Check manual for correct fluid may use tranny fluid rather than gear oil. I recommend using Royal Purple fluid or gear oil. This very expensive but will slicken up the shifting and extend bearing and gear life.

I had the same problem with my 1997 suburban.The transmission is building up excess pressure,its an internal problem that can only be fixed by repairing the transmission.However I drove my truck like that for about 4 years and got 300,000 miles before changing it by using a synthetic fluid and Lucas transmission additive.

Hard shifting after highway driving 1998 tahoe. After driving on the highway (mostly in hot weather) after coming to complete stop the car shifts hard at about 10 mph. Ramdonly does this from time to time....


sounds like your pressure control solenoid inside your trans is sticking you will have to have your pan pulled and have the solenods checked or replaced since it only fails at times it might check out ok when the pan is pulled.

converter clutch regulator valve is worn causing line pressure to rise to maximum in turn causing your harsh shifts. Sonax makes a repair kit for it or you can install a stiffer spring to make it work correctly
