Going to do a change this weekend, and a SSP Trans Cooler Install, an AMS Trans Cooler Install and an SSP Deep Pan, along with the SSP Filter. Essentially the trans will be dry except for the clutch basket and hydraulics.

I need help in figuring out how much to add, preference to underfill rather than overfill.

This is my current math:
Full Capacity of System: 7.0 quarts
- 1.0 Liter for Clutch Basket + Hydraulics
+ 0.5 quart AMS Oil Cooler
+ 2.0 Liters for SSP Cooler + SSP Deep Pan (as per Jeremy's recommendation of 2.0 to 2.5 Liters for both Cooler and Deep Pan)

Grouping like terms I have 7.5 quarts + 1 Liter = 8.56 quarts (8.1 L)

Is that enough? 8.56 quarts (8.1 L) + the 1 L in the clutch basket for a total of 9.61 quarts (9.1 L) for the entire system capacity?

The entire system being SST, SST clutch basket + hydraulics, filter, AMS oil cooler, SSP oil cooler, SSP deep pan

 

The SSP trans cooler added about a liter and the deep pan will also add about a liter. That's 8 liters for the entire system (6 liters stock).

Now on top of that you've put an inline AMS trans cooler too? So you're running 3 total coolers (factory+SSP+AMS)?

 

The AMS replaces the OEM.

 

The "math" seems correct. However when in doubt there is a factory fill procedure with the over flow plug at the rear of the transmission.

 

Is adding an AMS cooler + SSP cooler a bit overkill?

 

Not when people are still getting slow down warnings at the track with just the SSP.
