Brooke's 87 V10

[LTZ C20]

If the TV cable is properly adjusted then don't mess with it.

A properly maintained TH700R4 will run well over 150,000 miles trouble free.

Any modifications will void your warranty.
If you want firmer shifts you can change out the 2-4 servo with a "Corvette Servo".
A shift kit can be installed.  It will require you remove the valve body and precision drill the separator plate according to detailed instructions.  It may also require different sized check balls that will be included in the kit.

It does require what Hatzie has stated. Not worth voiding the warranty for personal preference. Does she want it firmer? My 700 shifted extremely hard, for that reason I'm switching some of the parts back to stock. Honestly I wouldn't open that transmission unless required (aside from regular services) regardless of warranty.

Brooke is happy the way it is. I'm the one that feels it should be a little firmer.

That's it in a nutshell. I think a little firmer would be better, but don't want to risk going to hard.

The servo and spring is a pretty simple task.  You don't need to drop the pan.  It can be reversed fairly quickly.
A shift kit is a bit more involved.  The valve body comes out and the separator plate is modified.  To go back you'll need a new plate.
As I noted above these will void your warranty.

An additional cooler is easier and will not void the warranty.  A Low Pressure Drop (LPD) plate cooler is temperature regulating and will not affect the line pressure enough to be a problem.
I'd add on a transmission fluid filter in the return line too.  Either a spin on with magnets on the outside of the canister or a real Australian built Magnefine filter.  Welding a drain plug bung into the pan would be high on my list too.
The pickup strainer in the transmission pan is a 100-130 micron screen.  A fluid filter is 25 microns or so.  The cold pressure drop is taken care of by a mechanical bypass in the filter.
Once you install a drain plug and a real filter in the fluid return line you will not need to drop the pan and change the strainer.  I drain and fill my 4T65E-HD on my '09 Impala with every oil change and replace the 25 micron fluid filter in the return line.  It's literally just an oil change.

Brooke has a welding class and a ABC's of auto class this year. Any ideas for projects? I'll try to get her to take a peak and chyme in.

Thanks for the ideas. I do miss having a drain plug! I like the filter idea, kind of a by-pass filter.

It's inline not a bypass filter.  An ATF filter will have a different bypass pressure than an engine oil filter.  The bypass valve is internal to the filter.  It keeps from starving the transmission while it warms up and it will also keep fluid flowing if the filter is plugged.

For the price, this is a good upgrade as well. You can get it with and without the summit logo for the same price. All the reviews for it are good. Adds 3 extra quarts and has a drain plug. I'm going to get one this week and drill and tap a hole for a temp sensor in the side. You can also get a magnetic drain plug for it, GM part #19133162, 3/8" NPT.

Also recommend this, since it doesn't come with a gasket. I'm also getting this.

One cool advantage of the sand cast pans is that flange gasket leaks become a thing of the past.  The pans also increase case rigidity.

2 of reasons I recommend it and am getting it myself.

Thanks for the suggestions. My wife took it for a ride tonight (and ended up chasing the neighbors cows) and she feels it's too soft also. We're going to have a couple other people we know drive it and get their opinions. I thought maybe it was just in my head, LOL.

If you elect to install a shift kit, avoid those that limit accumulator travel with spacers.

Last winter. There is a video playing in the snow I'd love to share, but it needs to be turned a 1/4 turn and I can't figure out how to do that or share it on here.

Thank you, I won't rush into it. I should have some time to research tomorrow. Any places in particular to look? I'll try to do a search on here 2morrow.

Be careful with the opinion of others who do not fully understand said transmission and it's functions/operations. They may agree with you based on personal opinion but without professional experience or training they may lead you to a solution that is not warranted or pointless. Have you considered taking it to a dealer and just asking for a test drive with a properly trained tech? Just asking for an opinion from a professional because you want to be sure it's ok may set your mind at ease. They should be more than happy to give it a run around the block, I know we do at work and we don't charge anything for a simple 10 minute ride like that.
