About to have a V8 vortec installed and thinking about a shift kit. My van is lifted and doesnt need to beat anyone off the line...would rather avoid the whiplash I'm hearing people mention. What should I do for a shift kit set up? Is it wise to do without it?
thanks

Re: What is the least aggressive shift kit?
I have a B&M electronic shift kit that I took off my 97 Astro before I sold it. The wires need to be attached to the ECU. I now have a 2002 Safari with Tow/Haul mode so I no longer need the B&M device.

Re: What is the least aggressive shift kit?
If you're referring to the 98 4x4 I'd do a larger boost valve and a Vette servo and leave it at that. The 4L60E is a pretty good tranny without doing anything. ![Dancing \:D/](./images/smilies/eusa_dance.gif)

That vortec V8 probably has a 4L60-E behind it as well. So they can definately handle it. Well except the V8 Version has a larger clutch pack but that's moot point.

Transgo without a doubt. Mine shifts gentler than stock I used the center values listed in their ranges, so your holes have a lot to do with it.

Re: What is the least aggressive shift kit?
I'm not a fan of shift kits. In most daily driving instances you don't need them, not want them. Who wants a thump at every shift point? A smooth transition is what an automatic offers versus a manual stick. A shift kit saves a tranny as it doesn't "slide" the clutches as much thus lasting longer, but for all intended purposes, most trans will last the lifetime of a vehicle anyway.
I just rebuilt a C4 for my 1963 Ford Falcon and did not use an added shift kit. It has an adjustable modulator and to be honest, it felt like a shift kit when first installed. I dialed it back into a smooth, cool and calm shift transition.

I somewhat agree with you about shift kits.The other part is the wear created by the hard hits to rearends,u-joints,etc.The part that gets confusing with my use is a Astro who's primary use is towing wt's from 2500lbs to 5000lbs.(the 5000 lbs is only limited times)The tranny planned to be used is a V8 version from a 1991 pick up.I have looked long and hard at TCI's parts and I am temped to go hard core for long life.
But I am going off topic here.D.D'ers I don't think need a mouth pc to go to the store.

Re: What is the least aggressive shift kit?
hello, im new here but i would use pcmforless.com and have him program a progressive tranny line pressure increase and also tune it up. i like mine smooth at part throttle and snappy at more throttle and thats how he programmed it. i had him tune my LT1 caprice and do the changes for the motor mods, n2o, gears, tire size.

Re: What is the least aggressive shift kit?
Transgo makes a corrective shift kit for these trannys . its not a hard shift like the HP ones but does in fact change a few internal parts ( boost valve etc.......) to give the tranny a renewed life & more power handleing capabilities .
