Installing new TQ converter should i go thru the trans?

You mentioned MTS Diesel, is that who you got the EPC solenoid from? Is it just a stock solenoid or is it modified? I can't tell from the description. It's cheap compared to most I've seen.

So all you did were the solenoids and the tc?

Yep

Yes the EPC was a modified stage 2 from MTS, if you talk to them they can set the EPC to a higher pressure, stage 2 was the most streetable they recommended its also the same one they use in there top built trans unless the customer request something different

Did you get codes when those solenoids went bad?

No, but i wouldn't say they where bad, the new stage 2 EPC solenoid raised the internal hydraulic pressure which is constantly higher now and can not be manipulated by the TCM below what it is set at. My truck is a early production 07 job 1 so i think it benefited more from solenoids. The new RCD converter performed flawless before the solenoids, the solenoids eliminated the 3rd-5th shift flare i had after i fixed the converter issue, and i really like the fact that the shifts are always crisp and firm due to the hydraulic changes where running before with just tuning, the tuning seemed seemed to get lazy the more the TCM started learning and making adaptive changes. Don't get me wrong this still happens but the base pressure is still high enough to prevent the trans from ever getting sloppy shifts. Hope that makes since...lol I'm not a trans guy..........

Neither am I but I see what you're saying. Where did you say you are getting these solenoids? Just incase I need to replace any more of mine

just curious, did you ever have the rev-slam problem? if so did these addtions change anything? that is my main complaint for my 08.

Those are what took out my trans. That was the last thing that happened before I lost all lower gears

I got the EPC stage 2 solenoid from MTS, If i did it again i would just get both from MTS, the direct solenoid is less with them aswell

No the solenoid's never cured the rev slam issue, but there are far less of them then prior to the changes.

It would seem so but here is another thought I have had. Because a stock trans can not lock as hard if you will and can slightly slip I think that is the key to not breaking hard parts. I have broken an intermediate shaft, two input shaft's and a converter. Until this most recent trans I have never had a trans slip on me. I want to go find a good core that hasn't been trashed and rebuild it with all new stock clutches and steels and stock converter or a well known used one not Suncoast. Some billet hard parts and see how it runs, how it tows, and how long it last.

You don't count, you gotta 450. Kiddin aside, I wonder if this ain't a 450 thing. Corbin's old 450 started going thru trannies after the stock one died. Last I heard, he never did get it figured out. I think he ended up selling the truck. Your theory sounds reasonable, but I ain't sure if it will hold true for a SRW 250 or 350.

Just wanted to follow up, little over 25,000 miles since i put the converter in with no issues. I think its safe to say i came out ahead just doing the converter and not the whole trans.
