On 09/14/07 at 16,566 miles I had my transmission serviced (band adjustment, fluid, filter) by a local transmission shop that I have a lot of confidence in. While in for the service I had a TransGo shift kit installed. Afterwards I posted my experience with the shift kit supporting it as the best single upgrade pertinent to driveability excepting perhaps the DC Performance Stage II tune.
To make a long story short, within the last couple of months I developed a problem of the truck intermittently behaving as though it was bumping the rev. limiter on WOT 1-2 and 2-3 shifts. More recently I started having the shift search under light acceleration on the 1-2 shift that indicates a problem with the governor pressure solenoid. My dealership replaced the solenoid under warranty. Doing so not only fixed the shift search but also fixed the intermittent indication of hitting the rev. limiter. The initial symptom of bumping the rev limiter being linked to the TransGo kit in combination with a failing solenoid is a symptom I've not seen on the forum so I'm posting in case others experience the same.
My dealership had no problem covering the repair under warranty.
Dan Cragin went the extra mile on customer service pertinent to working through PCM tweaks of the shift points and rev limiter settings even though from the beginning he believed (correctly) it was something mechanical in the transmission. He also hooked me up with Joe at Westminster Transmission as a resource. My local transmission shop spent quite a few hours chasing the problem both in test drives adn on the phone with TransGo. The service tech. at my dealership didn't have experience with an SRT10 or a 48re with a shift kit but provided excellent support in getting things back to optimum. My dealership works on a lot of Dodge diesel trucks and said they average changing one of the solenoids each day (replacement solenoid is not an upgrade).
Considering the failure frequency of these solenoids, going forward when I get my fluid and filter changed annually I'll just get the solenoid changed while the pan's off so I hopefully don't have to deal with this problem again.
Hopefully this info. is helpful if someone has similar experience. At 26,061 miles my truck's back to shifting fast and hard again, with no intermittent laydown/delay. I'm again very pleased with the TransGo kit. Oh yeah, the shop that installed my kit only drilled one hole in the valve body. The instructions allow for 1 or 2 depending on how much harder you want the shifts to be. Considering the experience with the failing solenoid I'd be concerned that having 2 holes for yet more of a pressure increase would have resulted in the WOT shift problems showing up sooner and worse.....but that's just speculation.
