cool, i need to drive around some more. When i pop it on 4 "3 on the cluster" I can still feel it go into 4th.
While driving, when i shift out from D to 4 the car doesnt downshift. Thats why i had the feeling that it's still acting like when the car is on D.

So basically "D" and "4" on the shifter / cluster will both be D on the tranny?

if you dont' plan on going over ~380hp, the 5spd would be OK. Larry @ SP built 2 5spd tranny to hold ~around 500hp, and both seems to break rather quickly (even with proper tranny cooling). IIRC, Mikal that has a gs400 tranny built to handle 500hp and is still running perfectly...you might want to talk to him if you're serious about going 5spd auto.

Just an update.... The car is running awesome right now. All I did was raise my idle to 800 and the car is great. No more hesitation, no more stalling, etc. I have one more thing I am gonna do. A resistor, inline with my coolant temp sensor. It should keep the car in open loop and will be easier to tune. Anyway, I will be on the dyno again next week and then moroso for a time slip. I might even go dyno on a "dynojet" to see the difference in hp for *****s and giggles. The dynomite I have been using is way more accurate. I'll be running some race gas and probably boosting around 25lbs. Can't wait. Hopefully low 12's. I need a tranny and tires to get into the 11's. Peace...

How much is it worth to know
If you look at the ignighter there is a blank hole in the connector with no wire in it. Pull a pin and wire out of your olf harnes and run it to the wire in the ECU box that feeds signal to the tach. I don't remember the wire off the top of my head, but if you have a schematic for the GS300 you sould be able to find it.

Well, we finally got Dex's car back into the schedule after months of hold ups (waiting for parts/other cars/short staffed).
Everything works! Return fuel system is operating perfectly. No engine light (so far 
).I'm gonna jump the turbo system to parallel operation and adjust the shift linkage tomorrow. Should be back in his hands by the w/e.
Thanks for the help everyone.

Trans shifts great! It's got the the 3 light/4 selector thing going on though. She's ripping! Boost is smooth even with the parallel operation. NO CHECK LIGHTS!
I did notice a little full load/full throttle high rpm hesitation. It's only occasional. I think we should change out the OE spark plugs. We'll keep you posted.
Thanks again everyone.
