Title: Advice needed - torque converter
Post by: franjo_66 on March 17, 2012, 04:09:10

Well I had a bit of bad luck today. Torque converter has split in two. Mine is the aluminum version, and I am sceptical as to whether it can be repaired. Am I able to use the later steel version ?

My car is a 1965 build 230SL. Chassis number is 113-042-22-009057

I see that adsitco sell rebuilt ones, but don't specify if they are aluminum or steel.

Any advice as to whether I can use the steel version or otherwise is appreciated

Regards
Frank

I'm pretty sure they're different and you have to use like for like. It's rare that it would split in two like that. ???

Hello,

Seems to me that some of the aluminum converters used a four bolt hook up to the engine flywheel flex plate and the steel ones used a six bolt hook up. If this is the case, a steel converter would definitely not even bolt up. A good used aluminum converter could be an option?

Thanks for confirming Dan & Joe.

I couldn't believe how that converter split like that. It was as though it was precision cut with a steel lathe !

Will get a rebuilt aluminium converter and hopefully that will be it. Auto had always performed perfectly, and there was never any debris or shavings in the fluid when doing a service. In fact fluid always looked clean.

Oh well, these things happen I guess

The aluminium ones are well known for failing. The steel ones are a direct replacement IF you have the same bolt pattern. If not you can swap the flex plate to take the steel converter.

Hi stick, yes I think the aluminum converters came in an early 4 bolt version and then the 6 bolt version. The steel converters were all 6 bolt versions.

So if I am understanding this correctly, I can use the steel version if I have the aluminum 6 bolt converter, otherwise I need to get the matching flex plate as well if I have the 4 bolt version

Thanks for the heads up

Also be aware that there are riveted hub steel converters and the later welded hub converters which are interchangeable.  The welded hub steel converters never leak.

Joe mentioned the riveted hub steel converter. If you do get one where the snout is riveted to the body have the seam and around the rivets welded. I only had to pull my transmission 3 times to learn that.
