The valve body upgrade is actually pretty simple, you just dropped the valve body and either did a swap or sent your's in to be modded. Usually cost about $1k. They do recommend a tranny cooler as well because the upgraded VB tends to make the tranny run hotter. |
Hmm. Well, it will be interesting to see if it makes a difference for the 7AT too... I think some of the shift speed must be tunable as is, given that it definitely shifts harder and faster when you use the paddles.
Does the ECU throw a code if line pressure builds faster than expected?
How much power was the 5AT holding before something broke?
