Ok, if that is the case, does it suffer from the same failure issues as the 4T65E? The forward apply band broke in mine, which is very common problem after researching it. Still want to know if the subframe design is the same or if they improved/changed it for the '00-'05 models, including the GXP ...

I have a 1999 Bonneville SE that I've owned since 2003, last year transmission went out and the subframe is shot and so is the passenger frame mount for subframe also. Car has been sitting in garage now for a year since I hate to get rid of it, but determined it is basically unfixable, or at least ...

Mine was the rear upper spring mount, which would be a easier fix than yours. They still wouldn't touch it. May have to go with someone who does work on the side.

What year is/was your Bonneville? Did you end up ever getting the spring mount fixed or not? Yes, the last guy was someone who just ...

I've found that shops won't touch suspension, and frame problems. I couldn't even find a shop to repair the rear upper spring mounts that had rusted out. I tried everything from a body shop, to a shop that does frame work. They worry about repercussions if things don't turn out well.

Thanks, yes ...

Had another mechanic turn down fixing the car, too much work with the tranny rebuild and the subframe/frame welding work needed done. I was hoping someone on here would be somewhat near my area and know someone or has done this type of work and would offer to help. I can get a shop to do the tranny ...

Okay, thanks! That is definitely the same problem. That repair looks pretty involved, finding a place to do that is the problem, transmission shops aren't going to do it, they would need to drop the subframe to get tranny out, then this type of repair could be done. I was hoping to find someone ...

The tranny needs replaced so all of the bushings need to come out for that, so all would be replaced, I've already researched that and know the parts needed. Not something I would be doing myself, as they will drop the subframe to get the tranny out and do it then.

As stated, the outer subframe ...

1999 Bonneville SE, 145K miles, owned since 2003, garage kept, clean nice original condition, never any issues except routine replacement items and maintenance, etc. Transmission failed in late March, driving home, just suddenly lost D and OD. Having researched the problem it is the forward apply ...
