Anybody know of a torque converter rebuilder on the East coast? I think Ken H. knows someone in Americus but he's gone for a few months. (Ken if you are around lurking E-Mail me when you get a chance). I was going to send my S/P to Manny for a rebuild but when I pulled the Ragusa pan there was way too much metal. I went ahead and pulled it down and found the gears stripped,output shaft stripped, planetary gears and the whole carrier eat up wasn't even worth a core. The only thing good in it was the forward and reverse clutch packs. So I had an working extra tranny so I pulled it down today. It was perfect no wear on any bearings or thrush washers. So im changing everything over with new seals clutches bands over to my S/P case. The only thing Im having problems locating is the variable pitch converter. I would even get mine cut flushed and rewelded if I could find someone to do it.

Ted - I'm not sure who Ken would refer you to in Americus. I'll ask him if we talk, but when mine failed I had help a GMC guy who lives out of state.

Maybe Larry Weidner will jump in soon. His rebuilder is the only one I will trust with my sp converter. They are more complicated and take special attention to detail to get them right.

Ted,
Send the torque converter to:
http://www.midwestconverter.com/
This shop was used by:
BobM
RobM
LarryW
JohnB
BobD
And AFAIK we're all happy with their product. They will send you a questionnaire asking about the vehicle and engine the torque
converter goes into, if you tow. They custom build a torque convertor to match your engine, vehicle, and tow. IIRC it will cost you
around $250 but I'm not sure about that.
They don't TIG weld the blades they furnace braze them.
Regards,
Rob M.

I'll second that. Midwest Performance Converter is the name of the company. Owned by Thomas Kenny. You can email him at tomkenny@midwestconverter.com
Phone is 612-724-3004. If you can, (and he is still around...not retired yet) try to talk with Dick Lewis. He is one sharp cookie. Several of us have modified our SP trans while apart by drilling a hole in the main case. I believe it is a specific size hole and is called "Line to Circuit" Talk with Dick about this. Dick...if he is still working...can be reached at 800-262-2063. If Dick has retired, speak with Tom.

Do tell of the modification.
I have most of the S/P back together but now would be a good time to pull it back down and drill a hole if it would be of worth. I bet Rob M. would know someting about it. I ordered a Dayco V/P torque converter and it will be here Friday. So i still have time for Mods if anybody knows of any more. I will be running a Temp guage and a trans oil pressure guage from now on.

Ted,
RobM had the good fortune to speak with Dick Lewis about the torque converter MPC built for him. Dick talked about the mod which as
best as Rob can remember had something to do with preventing the transmission or torque convertor from "starving for fluid in
certain conditions." However, he could be wrong!
Basically Rob has yet to read the section in the Maintenance Manual on the transmission and since, unlike you, he has never done
anything to, on, or with an automatic transmission other than change fluid he don't KNOW diddley squat about the way they work and
what Dick was kind enough to explain in great depth went clean over Rob's head!
He's a real dumb-a$$; he should have taken notes!
Regards,
Rob M.

Well ok then
Rob I figured you have been into these bad boys before since you have a switch pitch. Or have been around when someone was tearing into one. If you were around here I would be happy to let you get your hands all in my tranny there is a lot of cleaning that has to be done. You should have been here for the engine rebuild. Ive totally done the engine now the tranny and checking the Final drive while its out. I would just like to get this thing dependable to go somewhere distant. 2 years in a row not making Bean Station is taking its toll.I have the Switch pitch manual and have looked thru it and there is nowhere in it the drilling of a passage.

Ted,
I second Rob's recommendation. After burning out two Cad500 thrust
bearings ahead of the TC from Albany, I can't recommend them -- guilty or
not.

Ted,
For an explanation of the "line to circuit" hole and where it is located contact Steve Turnquist. His number is seven 63-seven55-one one34.
When you get the explanation, and location of the hole, could you please post it for us.
