Hey y'all.....
I'm planning to put in a shift kit when I change the tranny fluid, as I'd like some improvements.... Mostly I want to to feel better and last longer.... Gonna be towing a trailer (about 2000 lbs or so) and already have a cooler installed.....
Transgo makes two kits - the SK-4L60e and the 4L60e-HD2...... As far as I can tell the main difference is that the HD2 kit is described as giving "muscle car shifts" and also includes "gear command" which lets you shift up and down using the lever and holds the gear you choose to any rpm....
I've read this thread several times :https://www.astrosafari.com/viewtopic.php?f=70&t=14895
and it seems to give a good description of the ins and outs of installation of the HD2 kit, plus some add-ons, but then his description of how the transmission behaves afterwards sounds like maybe that's more than I really need to do to get what I want.... I don't need it to whack me on the backside every time it changes gears, but I do like the idea of it shifting cleanly without the waffling it does now....
Some questions I'd love to have clarity on:
Is the SK-4L60e kit combined with a corvette 2nd gear servo enough to get the tranny shifting crisply?
If I need the HD2 kit, do I still need a corvette servo, or do the spacers and springs that come with the kit take care of that job sufficiently?
If I'm understanding right, adding the Sonnax super hold 4th gear servo will let the tranny stay in 4th longer before downshifting, is that correct? If so, can I use that with either of the transgo kits?
What exactly does the "gear command" feature of the HD2 kit give me? It seems to me that I can already choose gears using the lever (though it will shift if RPMs get too high).... Would this feature allow me to hold 3rd gear up hills without downshifting to second by keeping the lever in 3rd?
Any insight would be so appreciated.....
Also, any thoughts on whether 'tis better to install a drain plug kit into my OEM pan, or buy a replacement pan with a drain plug built in....
