2016 Buick Enclave Power Train

When stopped on a incline and you step on brake the transmission will go out of gear ,then when you start off you have to hold brake till transmission engages, it is really scary , I have almost rolled back into another car several times . Went back to place we bought the car new , they said it must be a safety feature, it is not ! My wife is scared to even drive , love the car except for this !

My car shutters and shakes when switching gear. My mechanic believes it’s transmission and or torque. My mechanic said he has fixed at least 6 of them recently as well and is very surprised there is no recall

DRIVING VEHICLE WOULD NOT GET OUT OF FIRST GEAR. DECIDE TO GET VEHICLE HOME SO I TURNED AROUND AND FOUND THAT I DID NOT HAVE RESERVE ALSO. ON WAY BACK HOME TRANSMISSION MADE A LOUD CLUNKING SOUND AND THE CHECK ENGINE LIGHT CAME ON. WAS ABLE TO GET HOME AND PARK THE CAR. CALLED TOW TRUCK TO TAKE TO THE DEALERS. THIS VEHICLE ONLY HAS 23,773 MILES ON IT. DEALER HAD TO OVERHAUL 3-5-R CLUTCH HOUSING.

TRANSMISSION FAILURE AT 27,125 MILES. WHILE AT A STOP SIGN AT A BUSY INTERSECTION, WENT TO PROCEED AND HAD NO POWER TO MOVE. ENGINE WAS RUNNING FINE. GOT VEHICLE TO A DEALERSHIP AND THEY FOUND 3-5 REVERSE SNAP RING GROOVE HAD SHEARED OFF AND METAL WENT THROUGHOUT THE TRANSMISSION. DEALERSHIP INFORMED ME THEY HAD FOUR SIMILAR ISSUES IN THE PAST COUPLE OF MONTHS.

TRANSMISSION WON'T SHIFT OUT OF 1ST GEAR AND REVERSE GEAR DOES NOT WORK.
