Thumping when Shifting into 1st

[fost9508]

Can't beleive how great this website is. ATTABOYS to everybody and whoever started it.

Anyway down to business. I have an 88 mustang with stock transmission and it seems more often then not when I shift into first from a stop I hear/feel a thump which seems like it is right under me. I have checked the u-joint and it doesn't seem loose. I have talked to people I trust and they don't think it is a big deal, but it just doesn't sound right. Anyway ideas?

Thanks!

tranny mount wore out?

all the bolts tight in bellhousing?

Don't know to both Q's. First, I need to find out where the tranny mounting bolts are. Second "bellhousing" not sure what the heck that is. I have an idea but would probably sound more stupid trying to explain what I think it is then just pleading ignorance. Another question not sure how long this has been going on since the car is used, but could the long term effects of this be bad?

Thanks

Bellhousing = where your transmission meets the engine.

The transmission mount will be a the crossmember. It's a rubber section that bolts to your trany running across the car look under it and you will see the mount.
