Car Will Not Shift Into Overdrive, Runs Rough/Dies When Put Into Gear

Asked by Apr 18, 2014 at 08:32 PM about the 1987 Cadillac Brougham RWD

Question type: Maintenance & Repair

Hello All,

I have a 1987 Cadillac Brougham, which will not shift into overdrive.  It also dies when
initially putting into gear, unless I step on the gas.  After it gets going, and I stop, it just
seems to run rough when stopped in gear.  Runs smooth when idling in P & N, and at
all other speeds in gear.

I know it's getting old, and the overdrive gear gets worn over time, but I'm wondering if
this has to do with the transmission sensor?  Maybe something else?  It is throwing a
code, but I haven't checked it yet, and don't know if it's related to this issue.

Hoping to avoid a tranny rebuild... I think wishful thinking is better than not thinking!!!!

Get the code checked first. Might be the trans solenoid that controls the torque convertor like you said. Have it diagnosed before you start replacing parts.

My 1987 Cadillac Fleetwood Brougham Shifts Into Reverse But Not Drive ! The transmission oil level looks fine ! Recently I installed A Drive Belt ! It Ran Fine ! Now This ! What Adjustment Is Needed...Maybe A Sensor !
