For the converter, just an interruptor signal from a manual switch, torque converter is locking up no problem it’s the downshifting that’s keeps it from loading at lower rpms with this trans.I have seen a manual lockup mod here on OB somewhere...
I wasn't sure if the tcm had the service port like an ecm does. I thought maybe if it did a chip could be burned to modify the shift strategy to aid in dyno use or even towing. I'm kinda curious now. I might have to look and see on the spare tcm we have on the shelf. I know a standalone contoller would ultimately be a solution, but that's a big price for just some dyno pulls.I wish, the psds run the trans via the ecm where our trucks have a separate tcm. Only way I could see to do it without a manual valve body is to have the fipl output on a switch to fool the trans, and manual override for the lockup pin on the tcm.
There's probably a lot of good thing to be said about this too. Aftermarket could be much better than the factory set up.Nothing can be done with the factory TCM. The only fix is to ditch it. Go aftermarket.
Thanks Wes for all the hard work and putting up with me adding new items every week. The power in this thing is awesome! Looking forward to putting her to work soon. In the meantime, it’s off to paint for now.Well, big blue went home to Arizona Sunday, Daniel must be getting ready for a cannonball run because he made it all the way back home the same day about 1300 miles of driving.
Before the truck left, I replaced the original windshield, gave the truck a detailing and polished up the wheels. It’s quite the beauty, cannot wait to see this thing with all the body work done and fresh paint.
Sounds like the trip went well with the truck, seems like there’s a vibration now with the big single piece driveshaft at certain speeds unloaded, talking with my driveshaft builder and going through countless tsbs the other night we’re thinking we need to use some shims to adjust the pinion angle to closer to where it sits when loaded, where there is no vibrations. That’s a wrap on this project for now, hope to see pictures of big blue being put to work soon! Thanks for everyone following along with this project, and thanks to Daniel for bringing such neat project in and trusting me with his baby.
