zf broken mount

Can you take out the extention houseing on the truck ?
Or Do you have to take the transmission out and take it all apart ?
Trans came from a 87 with 4x4

By extension housing... do you mean the back half of the transmission case?
Basically... you're screwed. Transmission has to come out.
When you disassemble a ZF5 the last thing you're left with is the back half of the case. Literally, the front half comes off and all the shafts are installed into the back half.

Best best is either see if you can get it welded, or get a new transmission.

Yea I mean this part http://thumbs1.ebaystatic.com/d/l225...9ftMfWAIlQ.jpg
It broke off the right ear on the mount.

Im leaning towards getting it welded.

Just curious would this be a transmission shop job if I wanted to get the work done to change the part.

Or someone with basic mechanical skills can tackle this job like myself?

Thanks for your quick replys

If you wanna tackle the job yourself go for it. trans shop will charge you a fortune. If I had all the parts in front of me It could be rebuilt in a day. I had mine down to mainshafts and all other parts in baggies. ppl make it sound much more difficult than it is. attention to detail covers it all. pick up a good dial indicator and a shim kit for the main shaft and counter shaft. It may take a few tries to get it perfect but peace of mind means a lot to me on an investment. make it last. Look up a few rebuild threads, if you feel like its something you can do I'm sure a few here would lend some advice. I have a thread on here somewhere with my own issues, been into the trans more than i care to talk about lol.
