68rfe question

[quarterman]

I did a tranny upgrade for a customer with an 08 with dpf delete and a blackmax programmer. We put a triple lock converter and transgo shift kit the truck shifts good and doesnt slip but lockup will come out with very little throttle just when it starts pulling good it unlocks. Is there a fix for this or did I do something wrong.

built one a while back it does the samething...so if you built your wrong, then i built one wrong too!

Are you running a tuned TCM?

 

[quarterman]

I dont think so but how do you get it tuned

 

[J.Keith]

Give Ron at Suncoast a call. I know he sells the tuned TCM with his 68RFE's and can probably hook you up. Here's a link to the Cummins Forum (I know) with info on it. MHP 68RFE Transmission Tuning GP! - Dodge Cummins Diesel Forum

Modern Horsepower does the TCM tunning for sun coast. They make a custom tune for suncoast, but you can go directly threw them for anyone of there stages of tunning. I think there may still be a group buy going on over at cumminsforum.

B&G chrysler is the actual tunning source, it works wonders on these trucks, 25000 miles so far and its the best mod to date
