(10-05-2018, 12:11 PM)SilveradOM606 Very interesting input you all have. I'm fairly naive when it comes to swaps and TCs and their internals, etc. Although some of the good points you guys mention did cross my mind, simply as speculation. For instance, I assumed the 4L60E TC should be strong enough mated to an OM606 with only 6mm elements intended for daily driving; shouldn't that be a fairly reasonable assumption!

So I am using a standalone TCU (Fast EZ-TCU). I'm not sure if this was a good choice for use with the OM606. And I have wondered if the way the TCU is controlling fluid pressure, shift points, etc, is adequate for the 4L60E, TC, etc. But again, I assumed for daily driving there might be no harm if this TCU wasn't exactly the ideal one. I guess time will tell if I destroy the TC I'm currently using. If that happens, then I will start to custom fab a TC with internals for a diesel application.

Something else to add, I had been struggling to get good power, and I thought it might be the small turbo chocking the engine. I got a vnt turbo (GT23V) and power seemed to improve. So I started horsing around reving over 4k rpm which is when the motor came alive nicely, and incidently around that time is when my TC went out. I can almost say I heard/felt exactly when it happened. It continued to run/shift fine with hardly noticeable noise, although it would overheat on the highway.

I really want to go back to 2000 stall...but at the same time I want to use this cheap ($30) 1300 TC a bit more to see if it'll happen again. I will start driving it like I stole it again to see if the TC will blow again.

I understand there may be a money issue here but, if your TC fails all the debris goes through the transmission. so not only has the TC destroyed itself but the transmission as well. Money well spent getting everything right in the beginning instead of trial an error.

You haven't stated if the transmission is new, or if your running a transmission cooler. Everything plays into this, tire size, gear ratio, torque converter stall speed and gearing. Just trying to help out.

Does your controller use a speed sensor?

Talk to the company in the beginning of this blog. I think they will save you money and grief in the long run.
