Missing Trans Mount Bolts?

deputyjones · August 9th, 2006, 03:09 PM

I am looking at buying a 1987 F-150 4x4 w/4.9l and manual transmission.

I noticed the trans is leaking fluid, and when inspecting closer found the two bolts that secure the rear of the trans to the top of the cross member spacer are missing. The bolts that hold the spacer to the crossmember are there, but the trans is basically loose from the cross member.

1. Would this cause the trans to leak fluid? I wasn't sure where it was leaking from. There was trans fluid all over the trans.

2. The dude has been driving it this way and do you see this causing any serious damage to the driveline by him doing so?

Thanks for answering the n00bs questions

only way I could see it being the problem is it has rattled around for so long that it took out the rear seal. Is it wet at the back of the trans or the front?.

Definitely towards the front. Did not appear to be any leaking from the tail. It also looked like somebody had tried to seal the front of the trans with some sort of putty in the past without much success.

Thanks for the reply.

That isn't a good sign

Yeah probably means it has been leaking for awhile. I would question why they wouldn't have the brains to put a couple bolts back in the mount? Was the mount broke or just missing the bolts? Was the engine and trans removed ?

4.9L is a great reliable motor lots of torque not too many RPM's or HP but works well and gets decent MPG. They are a dime a dozen though so don't go out on a limb with this questionable one unless you can get some clearer answers.

No idea why they would not have put the bolts back in unless when whomever puttyed it just thought it was leaking and did not know the bolts were missing.

From what I can tell the mount is not broken just bolts missing. However, the trans is now about an inch offset so I can't tell if the bolts were sheared off inside it or not.

Good advice and thanks for the replies. You are right the 4.9l is a great engine and a dime a dozen so I will keep looking.
