Lincoln towncar possibly transmission problems

Question From superdoc28 on Lincoln towncar possibly transmission problems

Hello everyone, I have a 2000 lincoln towncar executive, recently i got rear ended by an infiniti i30 and there was light cosmetic damage(no dents) to the back bumper its a strong car and some muffler and underbody damage. After the accident as i drove the car home, it wouldn't accelerate past 40mph, the speed would slowly go down after hitting 40 and the engine would just rev up if i pressed the acceleration and it would only go back up if the speed hit 20mph, only to go back up to 40mph. My question is this, could this be due to the accident?? How would i go about proving it was due to accident? THe insurance company is only taking responsibility for the back damage and saying that this was not due to the accident. Can it be due to the accident? and what diagnosis tests would i have to ask for. Any help would be greatly appreciated.

Response From Hammer Time

First........... you have to determine what happened before you try to figure out why it happened.

Response From superdoc28

ok....so how would i go about doing that? its my only car, i know its old, but it was running decent before the accident.

Response From Hammer Time

The only way you are going to find out is to get it to a transmission specialist so he can determine what is going on there.

some muffler and underbody damage.



So your saying top speed is 40 mph? Did you make sure the exhaust pipe wasn't smashed or kinked shut?

Response From Hammer Time

I thought of that but this seems to point away from that.

the engine would just rev up if i pressed the acceleration

Response From Discretesignals Top Rated Answer

I'm having a hard time trying to make sense from his statement. It could be revving up either because the transmission is slipping or the tranmission downshifted, but if the exhaust was corked the engine shouldn't rev up beyond how ever much the exhaust is restricted.

Have you checked the transmission fluid level? How damaged is the exhaust system?

Response From superdoc28

not sure how damaged the exhaust system is, could a rear ending cause the transmission to get damaged like that though?

Response From Discretesignals

Well, if they are replacing the muffler it must have gotten pretty screwed up in the accident. The transmission is in the middle of the car. Really the only way the transmission would get messed up in a rear end collosion is if the driveshaft got pushed up into it. The exhaust system runs around the transmission though, so it could have gotten into an electrical harness for the transmission. Only the person working on it knows what is going on here.

P.S. you don't have to make a bunch of one lined posts, you can edit and add additional information to one post. I don't need 40 emails.

Response From superdoc28

The problem is the insurance company isn't even willing to diagnose the engine because they don't believe its related to the accident since its not a front end damage, i have to take it to a third party and get a diagnostic which proves somehow that it is accidental related, so the insurance can even consider it, would pep boys do something like that? what type of mechanic is the right person to diagnose and let me know its accident related, so i don't go to multiple places and waste money i don't have.

Response From superdoc28

when i was driving the car after the accident, it just felt like it wasn't going into 3rd gear, after second it was stuck, as far as i could tell, but not an expert in cars

Response From superdoc28

to be very honest i have no idea, i do know the body shop from the insurance company are in the process of changing the muffler.
