1993 suburban 4x4 hard shift


It may be a vacuum leak that is causing the high idle and shifting problem. Check all the vacuum hoses for cracks or to see if any have come unplugged. Hope this helps.

High idle shifts hard but idle will go back down but shifts hard


You'd probably have to take it in to get it diagnosed, but I'm going to guess that it's the electronic throttle body.
The throttle body and throttle position sensor are in the same unit and if one goes bad, you have to replaced the whole thing.

This will cause high idle, stalling, hard shifts and irratic throttle.

My 2000 gmc sierra z-71 has started idleling at about 1300 rpm after driving for a while. when i turn it off and restarted it would idle fine for a while then start idleing high again. it is getting to...


I assume the check engine/ service soon light is on. Commonly the MAP sensor is the culprit, but can be TPS, CSS, even a buggy O2 sensor. Only way to be sure? (light or not) is to scan it.

1993 F150. Idles very high when cold but will


sounds like 2 different problems..about the high idle,for example my 94 Bronco had a problem with the throttle sticking,it wasnt closing all the way,so i took apart the linkage at the throttle body and found that the shaft that the linkage pivets on was dirty so the shaft would not move easily on it.If i could put a picture on this i would,but dont know how..the part of the linkage im trying to point out i believe is where the cable connects from the gas pedal,on top of the shaft is a C clip,pull off that clip and pull the shaft off by turning back and forth while lifting at the same time.clean the shaft with sand paper or emery cloth and grease and reassemble...now for the shifting hard and check engine light,most likely its the vehicle speed sensor bad,thats if when you put it in gear and it hits hard and when it shifts into the next gear it hits hard.That sensor is about $35.00...you shouldnt have to worry about resetting the computer,an OBD11 computer system resets itself after so many revolutions of the engine,in a Ford

My 928 automatic shifts hard like it as shift kit installed


The transmission shifts (hard or soft) based on the engine vacuum it is receiving. So if you really put your foot down, the engine vacuum will decrease (less vacuum), this signal the trans that you are at high power and the shift shoul dbe quicker and sharper. Conversely, when you are loafing around the trans shifts softer due to a lighter foot (and higher vacuum). If you have a vacuum leak or a disconnected vac line the trans sees every shift as though you are at wide open throttle. You have a vacuum leak somewhere so tha the trans is not receiving any vacuum at idle etc.

Trans


Does the engine tack high? If so, then your engine is idleing too high causing the transmission to shift hard. It could also be the universals. Check to see if they are going bad. Another suggestion??? Does it have fluid in it??? Just asking... LOL!
