Trans jumps out of gear
Iím looking for any suggestions to figure out why my transmission jumps out of gear. Iím not finding much of anything in my research so far, so hoping someone here has experienced the issue.
My motorhome is 1995 Fleetwood Pace Arrow built on a 1994 F-53 chassis with a 460 V8. It has 63k miles. Intermittently, the transmission jumps out of gear. After a short time, from nearly immediately up to a couple seconds, it goes back into gear. Based on how high the engine RPMs jump up when this happens, it is more than just the overdrive dropping out. It acts like I suddenly shifted into neutral.
Trans fluid level is within operation range. The oil does not look burnt or dirty.
Occurrence is random. I havenít been able to isolate the circumstances to make it happen. Sometimes it happens at the beginning of the trip. Sometimes it occurs after driving 5 or 6 hours. Sometimes itís when raining. Sometimes itís when the roads are dry. Sometimes itís when under a ďloadĒ (i.e. climbing up an overpass) and sometimes when thereís no load (ex: going down the overpass hill).
This started about 2 years ago. For a long time, it would happen once in the entire trip. It is more frequent now, happening multiple times in the trip. I have found that if I pull over, shut off the engine, then restart, it resolves the issue for a number of hours (usually the rest of that dayís drive). For example, I drove it about 6 hours total yesterday. At 2 hours, it started dropping out. I did my ďpull over/kill engine/restartĒ bandaid. It worked fine the rest of the day.
The intermittent behavior suggests a poor electrical connection somewhere or a failing electronic component. Iím thinking if it was a mechanical issue, it would not be intermittent. Also the ďpull over/kill engine/restartĒ bandaid would have no effect on a mechanical issue.
Has anyone had a trans do this?
Thanks much in advance for any suggestions.
