Default Which shift kit?

I have a 2000 t.a. that I'm ordering parts for to do a basic engine rebuild on and while the engine is out I'm gonna put a 3200 stall in. I was wondering how beneficial a shift kit would be to install while I have it tore apart and which one is a good kit for the money.

If it's torn apart you might as well, but it's really up to you. A tune can do a lot towards shift improvement also, but a shift kit can't hurt. Transgo HD-2 is the go to option.

I've got tune through hp tuners already. But where is a good place to get one of those at? And also since I'm at 135,000 on the clock would it be smart to go with a rebuild kit while its down?

I believe the Transgo HD2 kit is $80 on Summit.
Note that it includes optional internal parts (high RPM springs) to use if the trans is being rebuilt and you plan on shifts above 5500 rpm.

The Sonnax HD 2-3 shift valve recommended is by thunderstruck507 is HIGHLY recommended as it reduces load on your sprag and lets you drag in [D3].

Note that the shift kit requires removing the valve body and replacing springs in it. If that is more than you are comfortable with, just install the Sonnax 4060E-LB1 boost valve ($25) which only requires dropping the pan and using a pair of snap ring pliers.

Some of the trans builders here don't recommend installing a shift kit into a high mileage trans like yours. I think it comes from problems where they install a shift kit for a customer, the trans blows up (would have anyway) and the customer then blames the builder. Personally I would install the shift kit, but also plan on buying a new separator plate (Transgo Universal for $25), Torlon ***** ($10), new accumulator pistons ($10) and a reseal kit ($30) for those pistons, the servo, etc.

You might also consider the Sonnax Performance Pack (shift kit) which includes nice pinless accumulator pistons, Torlon *****, the Servo release check valve and other goodies. It is about $125:

Hope that helps you decide which way to go.

If I go with that Sonnax Performance Pack, would that be all I need as in a shift kit?Sorry I'm not very good with the internals of transmissions let alone automatics. Also what would be a good rebuild kit to install while I'm at it?

Here are some recent threads on rebuild kits in which I participated:

With a 2000 trans you will want a new sun shell and likely a new reverse drum; do pick a kit with those, or add them in.
