Rebuilt Torque Converters!

I know I'm tired and really do not mean to sound like an ***, but you really need to do a search. ATS, DTT, and I think Goerends(sp) all make brand new TC's for our trucks that are head and shoulders above stock or rebuilt.

I can't seem to find one for Goerends right now.

Just a question then why do they want the old ones back for a core if they build all new converters then? They still use old parts from them and they are not all new from front to rear… Some may use new cases (very small number) but not all that are sold to us are!

The parts that are reused are not wear parts. They are carefully inspected for any defects that could become problems. In the many years I have been in the industry I can't remember seeing any common failures due to rebuild. The trick is to choose the convertor that is up to the task you are asking it to perform. Do not buy a cheap part and expect it to work well. I have been involved with DTT for many years and am very satisfied by there product in a wide range of high performance levels.

I agree with proturbo. They don't need a core back if they don't use them. I know atleast one of said companies machines the stators. Most of the pump sides of the convertors are re-used (cases) with billet covers for the clutch surface areas and so forth. Even so, with regaurd to the question about the stressed components, the input shaft on the transmission takes most of the large shock loads involved with lockup. The converter areas that are reused only handle pre-lockup "fluid coupling" loads, not one-to-one engine load transfer. This reduses stress on these components to an acceptable level to allow them to be reused.

This is just how I understand it. . someone in the biz could probably explain it more authoritatively.

Wow... a little behind on this post... .



I've been to the Goerends shop. They cut the converters open, and only use the front cover. They then take and weld the fins to the case. The factory doesn't weld them very well. The rear cover is a billet unit that they have machined. The Stator that Dave uses, is of his own design.

Ditto what Josh said. I don't see that big of a deal w/ reusing the front cover.

LOL After re-reading my post this morning... . I said front cover 2 times... when I ment front and rear covers. The front cover is the one that is saved. The rear cover is the billet unit, the stator is custom machined

Oops, let me correct that. there is no reason NOT to use the parts not affected by wear or stress.

im sure we are paying not just for the parts. but for the time that those companys have put into designing and testing the converters. just my . 02.

This is one of the main reasons that I went with DTT 4 years ago. The milled stator. I had a BD milled stator and at 2400 rpm it was like running into a wall. If you don't have forced lock-up that's it. Dtt REPLACES the stator with one of his own design that makes lockup irrelevent. And the transmission still runs cool out of lock up.

Ah yes, the BD milled stator. BD used to (I really hope they aren't still doing this) take a stock stator and cut the back of the fins down to change the fluid coupling. This does exactly what you've described, Dave G. showed the pieces (stock not BD stator) to me and explained the relationships and the fluid coupling. He also showed me what BD was doing and why it didn'twork too well.



The Goerend stator starts life as a thick aluminum plate and spends a few intimate hours with a CNC mill. I've been around some CNC cells before but this was pretty cool to see plus I got to catch up with another TDR member (the machine shop owner) I hadn't seen for a few years.



Dave builds his own T/C's and he has all the parts there to see. If you are going to get one of his trannies, it's worth the drive to meet him and see what goes into it.

To be honest at the time of my purchase of the BD converter it was the leading edge tech on the 47re :-laf (1998); this was before DTT, ATS or any other builders.

I know, I lost a trans in January of '98 and the options were very limited. BD wanted $675 for their T/C! I installed a new stock T/C and a new stock trans that did have a lot of updates. I got the stuff discounted pretty good but it was still a $ ouch!
