Thread: Reinforcing a 32v Transmission case

Hi all,

looking at anyone who has done this. Is there a weak spot in the housing near the left hand side cv? Is it worth doing? . Looking at this while my box is in bits waiting for some upgrades. i may try Mr Kerr's "launch control" once its back together one day.

Here's a couple of photo's i've collected...

pro's/con's?

I purchased a transmission that had already been case welded. I believe it's the most common spot for the case to crack under wheel hop. It is there to strengthen the transmission for that reason. Only cons I can see about this being done would be who's welding it and how they weld it. Dave

looks like tig welding, and a decent job at it.

Interesting. Is this done with the bell housing separated from the tranny or as is? Does it have to be machined flat afterwards.

First option looks like less weight

A more simple way is to weld a brace onto the motor mount/shifter bracket and bolt the other end to one of the 14mm bolts by the bottom of the oilpan. I used an old altenator bracket for this on my car. I been using this for over 10 years with no issues. I did weld a case before but I was breaking gears so much I had to find a easier way to do it since I would have spares ready to go in when I break them. I also was a little skeptical about the case becoming warped from all of the heat during the welding process.

To weld it you have to seperate the case, remove the seal and the bearing cup. Then clean out the gaps and fill them with weld. Back when I got mines done I didn't have a tig welder so I paid $150 to get it done.

My bracket was free.

Just another option.

I did this as well way back in the day...the tranny is currently out if you need any more pics. I also had the gears cryo treated and shot-peened for added strength when I had the Quaife installed.

if you could post up pics that would be great. seeing i have my car down due to tranny problems i minus well beef it up while its out.
Thanks

I have done this countless times.

It requires complete dis-assembly of the trans, removal of the bearing in the bell housing so that you can get the plastic oil director out. Then you can pre-heat the trans and tig weld in the aluminum insert. This is mainly needed to prevent the case from cracking due to wheel hop. Most cases are cracked from launching at the drag strip.

Have Fun!

more pics please.

now this bloke knows!! i rang a local engineering place i trust, and he said much the same thing. pull all the stuff out of/off it, heat it up, and weld away.machine flat. he's done a stack of v8 drag racing stuff. i'll post up my pic when its done.
