That car sounds like its running a Rx2 jatco 3speed with billet valvebody, servos and other tricked out internals... Here's a quick run down on a Keas Jatco
Baseline model we offer is a 350kW (470hp) Transbrake model. From there you can option up better internals.
Core availability is an issue over here (the Rotary Model has a unique Valve Body and Servo/Piston set) so if your wanting parts then I will need your Valve Body and Intermediate Servo/Piston set for reworking.
Your basically dealing with a C4 that is already 98% rollerised, requires minimal Lubrication modifications and interchanges parts with 90% of all JATCO 3N71B and 4N71B models. We offer tech Sheets for Trade Customers showing our modifications during rebuilding.
Torque Converters
Choice of Hi Stall will greatly depend on Engine Porting/Turbo specs and desired results.
Generally Speaking:
Smallish Turbo and a mild Port= Reworked JATCO 9"
GT35-40 to GT42R with extend Ports- JATCO 7.5"
Larger Turbo and/or Bridge/Peripheral Port- Toyota 7". Highly recomend GAS to stop start line delays during spooling.
Prices in AUS $ (x 0.79 to convert to US$)
2nd Hand JATCO R3A $200.00
350kW Transbrake 3 Speed JATCO R3A $2,200.00
Options
Lift Rating to 540hp- VASCO Plus Billet Input Shaft $300.00
Lift Rating to 600hp- VASCO Plus Billet Input Shaft $300.00, Chrome Moly Nitrided 4 Pinion Forward Planetary Set $300.00, Thick Wall Cast Alloy Pan $220.00
Parts
Transbrake Valve Body Assembly $700.00
Billet Servo Piston $70.00
VASCO Plus Billet Input Shaft $300.00
Chrome Moly Nitrided 4 Pinion Forward Planetary Set $300.00
Thick Wall Cast Alloy Pan $220.00
Torque Converters
JATCO 9" $800.00
GM 8" $1,500.00
JATCO 7.5" $1,200.00
Toyota 7" $1,600.00

Interesting.......
would like to hear more about what was changed/modified in the tranny.... lets see how his goes then maybe I'll consider sending mine out to have the same mods done... My Rx2 will be making conservative power so I don't need a crazy race auto & stall

Eric's right a friend gave me the jatco out of a 1967 with 60,000 miles then he moded the valve body with springs and check *****, stuff i dont know crap about.
He runs one in his auto cross car with a 220 c/i supercharger and its held up for years and about 500 h/p in a mg miget. I have the stock converter stalled higher but 38oo stall isnt high enough for the torque i had plus i have 29.5x10.5w slicks with 514 gears. I need to go turbo and 6,000 stall with break and then the trannie probley wont hold up.
If i find the money i was going to contact carabiean trans they have the parts!

I'd think you could find some in the states who could re-stall that converter. The trans brake, I'm not sure about though.
I just wish I could get my hands on one of those transmissions. Charlie, do you know anyone with one laying around ? Let me borrow yours since you won't be running that turd for another decade.
