G2shuck modified dd solenoid review
Ordered up a modified dd solenoid from Gary, after a couple weeks of it being in the mail loop it showed up. Got it installed in a jiffy and did about 20miles on it right after. Stock ecm/tcm, 58v ficm with atlas 40. Within the first two miles I could tell a noticeable bump from 3-5, it was faster into 5th from 3rd. My stock shifting strategy seems to really suck but it felt like the 3-5 shift was tuned after I put this solenoid in. Putted down the hill and got onto 80, got on freeway at about 3/4 throttle and the 3-5 shift is officially the firmest/crispest/fastest shift in my trans. I had a gogo solenoid a year ago and drove 400miles just after installing it on a stock ecm/tcm and this solenoid has a noticeable more crisp/quick shift on stock ecm/tcm.
I'll be loading up my spd written for a modified dd solenoid next week, Ill follow up in this thread once I get a couple miles on that tune with this solenoid. This trans is also about 5k miles old fwiw. I would highly recommend this solenoid. I was definitely impressed after the initial 20miles. No flares, one jolt in town, probably learning but other that its nice to have a fast/quick/crisp 3-5 shift. Thx Gary!
