After driving it a little more this morning it seems like its lagging going from first to second. Did I do something wrong or not seated rite or is this a sign that I'm gonna lose my granny soon? It didn't do this until I put the servo in

Check the condition of the fluids in the tranny. I have seen that the pistons and some of the check balls in the tranny do stick and cause some delayed shifting--and that would be unrelated to the servo.

Had the tranny flushed yesterday before I installed the servo.

Going from 2nd to 3rd doesn't do it as bad and 3rd to 4th don't do it at all

I never experienced that with mine. Also, I never had my trans flushed. I just do a fluid and filter change, no back flush. Some people have reported issues after a trans fluid back flush..... Possibly the back flush dislodged some dirt that didn't get flushed out???

Just wondering if it does it all the time on the 1 - 2 shift, or is it under heavy power, or under a very light load?

Under heavy power it doesn't do it as bad. Just with normal driving

Well after driving it today it seems to be shifting like it should. So what ever it was has fixed itself. Thank you for the opinions and help. This thing is the best mod so far that I've done to my rig

Good to hear. thumbsup.png I wonder what it was that caused that issue? Maybe something like dirt or sludge was dislodged during the back flush? No idea....

That's what I'm guessing as well. If it kept up I was gonna stop the pan but it came out of it. I just added a thing of Lucus stop slip this morning where its got over 150k. Just a little extra precautionary act. My 96 sierra I had I put a thing of stop slip in with every flush(which was every fall) and it was still going strong at 248k.

Glad to hear the install went well! Definitely the best thing one can do in an afternoon! It was recommended to me by a mechanic to never had the trans flushed, only do changes. Heck even my wifes crv recommends you get a case of fluid, drain, refill, drive 5-10 miles and do it again until you put the last 3 quarts in. Thing only looses 3 qts per change so that would be expensive in our rigs.

You ain't kidding it would be. I always do a pan drop when I first get a new rig then flushes after that. It still "lags" sometimes going from first to second with little throttle but if your on it it goes rite in nice and firm. Fluid looks all good so I'm just gonna keep an eye on it for now. Definitely doing this swap when I get a different rig. I had to take my programmer out because it actually performed better without it.
