Re: Crown victoria
Years since I had this problem , but was taught on numerous auto transmision courses it was o.k over a short distance . Things may have changed over the years , but on checking out of curiosity found this from elsewhere on same subject ,
" For a rear wheel drive automatic trans, you need to drop the drive shaft at the rear ujoint. Should be pretty straight forward. Do not pull shaft out of the transmission, but then tie the rear of the shaft up securely so that it does not drag. If you do not do this and tow very far, you will destroy the trans and seals.
P S I always put the cups back on the joint and tie a rag around it so that the needle bearings inside the cups do not dislocate.
I pulled up the '04 Towing Guide for the Crown Vic/Grand Marquis/Town Car/Marauder. It says you can leave the rear wheels on the ground up to 35 mph for a max of 50 miles. "
Opinions seem to vary .
