SOURCE: Jeep Grand Cherokee Limited P0700 diagnostic problem

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.

SOURCE: Very rough idle on 2002 Jeep Grand Cherokee Limited Edition V8

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

SOURCE: i have a 94 cherokee limited 5.2 v8. which transmissions are come

The 46rh is a hydraulic transmission as where the 46re is an electric transmission. With minor wiring you can replace the 46re with the 46rh but not the other way around. Your transmission would stay in limp mode and wouldn't shift out of 2nd gear. So the answer is no.
