i have a 1999 jeep grand cherokee ltd. (austrian assembled, right hand drive)

just in the last day or two i have notice the trans slipping between gears..

seems to just rev a bit between shifts from 2nd 3rd etc....

fluid seems ok, but I'm going to check again incase i haven't checked it the right way (in neutral on flat with engine going)

anyone have any ideas ?

ok, trans fluid is correct, red colour and smells normal.

trans is revving between gears and there seems to be a small bit of a shudder too

no trouble codes showing, took battery off for 15mins this morning and it seems better today, but is still noticeable
