Transmission Not Shifting Correctly on a 87 Colony Park

I have an 87 Colony Park with just under 39000 miles on it. It hadn't been started or driven in over 7 years so it needed a lot to get it going again but now it runs great except it's not shifting correctly. I drove it about hundred miles as mechanic told me to and now it's not going into O/D. At that point it just shifts out of gear and the engine revs and I have to shift down to 2nd to get the transmission to engage again and it won't even go into 3rd. The only thing I can do is stop the car, shift into reverse and then back into drive and it works fine up to the point where tries to shift into O/D again. When I first started driving the car it was a little rough shifting down from O/D when I accelerated to pass or going up a hill so I just had the transmission flushed and the problem I have now started almost immediately.

I'm no mechanic and I'm not going to try and fix this myself (unless it's something like hose or something else simple) but any ideas anyone could have would be helpful. I guess I'd like figure out if the transmission it shot or if it could be something cheaper (I hope). Any ideas?

Thanks...Jeff

Re: Transmission Not Shifting Correctly on a 87 Colony Park

I've been away from the older Crown Vics for quiten a while so I'm not up to speed on them but 87_Crown_Vic comes in here once in a while and knows them pretty good. Meanwhile watch this video. YThose throttle cables sometimes break and they can cause shifting problems.

Re: Transmission Not Shifting Correctly on a 87 Colony Park

take a look at where the throttle cable connects to the throttle body... there is the throttle cable that opens the butterfly and another cablae that should be connected to the arm also that pulls out toward front of the car. many times the grommet goes bad since it is plastic and gets brittle with age. when it gets brittle, it crumbles and allows the tv cable to fall out where it needs to be connected to the throttle arm. when that happens, the transmission runs at low pressure and burns up the transmission. sounds like that is what happened. sad thing is it is mostly overlooked and that $3-$5 part not being changed causes a $800+ rebuild
