1 Hour with DTT Trans Build

[Giachino]

I've got a little over an hour with my newly built up DTT Trans..... all i can say so far is AWESOME!



Installed: Single Disk Converter, Valve Body, Billet Input, Billet Flexplate, Shift Enhancer, 2nd and 3rd gear stuff, Billet accumuator and piston... . other misc... . little over $4k..... Installed by Fred Swanson in Arizona (He's been great!)... . truck has 12k on it.



What i noticed (Smarty Beta 4. 4 on level 3):

- Get's the power down, no lag, no wait... . direct connect, punch it from any gear and it just goes... no more 50mph downshift to 3rd and wait for the mph to climb as the tach is at readline, no more slop... . 3rd and 4th lockup (T/H Mode) is very smooth as it's already tightly coupled...

- Firm Shifts 1-2 is the firmest as he didnt use a spring on some part..... it chirps the tires in 2nd without effort, 2-3, 3-4 are firm..... warning not a wife favorite... ... but she gave it an 8 out of 10 on the worth it scale

- Fred noticed one issue in 30mph steady cruise... . hunting between 2nd and 3rd..... and he saw a instant pressure drop... . going to contact DTT and hopefully fix next weekend... . it's not a smarty thing... we returned to stock and it still did it!

- If you want too, it'll smoke em out

- On the test drive with Fred, he said dont worry about the trans and did a 2wd boosted (5psi) launch and lit em up for 40 feet... ...

- From a stand still, no brake launch, it'll spin em and chirp 2nd gear (Not sure what Tq Mgmt Beta 4. 4 has in it... and remember, level 3)



Next Round of Testing: Mileage changes, slow speed / traffic driving, play with the different levels on the shift enhancer, try smarty at level 5, 7 and the 3. 08 wild... ordered a gdp... . will wait for that to try level 9... .



From what i've seen so far, worth every penny and recommended to anyone with the $'s and planning on keeping their truck for more than a year!

I have been having a round and round with the dealer about my 06. I have the down shift problem you mentioned. Mine waits until about 45 to down shift to third. Dealer says it is working fine. I don't think so! A handful of times it has down shifted at what I consider a more normal 55mph in T/H. Most of the time the transmission will allow the engine to lug down to 1100rpm in T/H or not. Owners manual says it is supposed to down shift in T/H with constant braking. It has done that maybe a half dozen times.
It never seems to shift consistently. Sometimes shifting harshly with T/H off like a locked shift and smoothly with T/H on! I think I have a valve body problem. I also think they are waiting me out on warranty!

You might call DTT and talk to them! Brady at I. I. said there shift controller cured all the issues in shifting in the 06' and above trucks.
