Oh, is this not good for the transmission?
Back on topic, is it possible I damaged my pump by running it dry when changing fluid?
How hard is it to change the pump, can it be done in the car?
Cliffs: car does not shift into 2nd or 3rd when cold for the first 1/2 mile. After that, it's fine.
It is possible, but depends on how long it was run dry. If it was only momentarily, the residual fluid in there would have kept it lubricated.
You have to pull the tranny, the pump is driven off the input shaft.
Put a pressure gauge on it before making any decisions.
does the trac light (not the trac off light) coupled with the lose of manu function and o/d off light blinking indicate a malfunction in the transmission? is it perhaps too much fluid or the wrong fluid?
I have been having a problem with my built auto. The converter locks and unlocks randomly. It will fine for some miles and then it just locks up and eventually unlocks. What could it be? Something wrong with the lockup solenoid?
It has a aem v1, ill try to disconnect the battery and see what happens.
Got a pretty important question
I was talking with a rep from ATF about the ATF built A340E, and I asked him what fluid do they recommend for their built Toyota auto, and he suggested Valvoline Dexron 3 (non synthetic). But after going back and rereading this thread I noticed this post, and wondered if this was true or not. Also wondered if it would pertain to an auto that's been drastically modified such as the ATF trans.
PS: mods why isn't this thread a sticky by now, tons of great auto info!!
I flushed out all the Dexron, and replaced it with Toyota Type IV, and it's never done that since.
I also agree this should be a sticky! We might eventually move it into the tech section to keep things less cluttered, but for now it'll stay here.
ransmissions running on AEM:
1) Timing HAS to be less than 6 degrees of timing between shifts. This will ensure the longevity of the transmission. Each car will be different as to how quick the timing will be ramped back in. Doing this incorrectly will result in a slow vehicle. Please ensure that proper professional tuning has been contracted. We recommend tuning by Justin from Tuning Concepts ([email protected])
Instructions on doing a burnout without breaking the 2nd gear sprag:
Stock ECU Equipped Cars:
Place the car in 1st gear. Do the burnout ONLY in first. Shifting to 2nd can cause you to roll the sprag.
AEM ECU Equipped Cars:
Press the MANU button .Place the car in 1st gear and do the burnout. If you do not use the MANU button, the transmission will go through the gears as normal even if the shifter is placed into 1st gear.
Hello need help here.
just finish install the AEM2 my supra MK IV has stock TT and with AUto Tranny.After fininsh the dyno and maps when i drove back the transmisson shift very hard from R to D
The Shift gear occurs below 1,000 RPM ....
My question will be it be better if i just follow the above set up?
So I've upgraded to Titan Stage 2 auto on 3.5k Stall on AEMv2 with a nice cooler. It been good step up to stay the least.
I've sacrificed my life financially, career wise, socially and touch of woman for the sake of keeping my Supra project alive.

The guy from ATF told me it was fine to run Toyota T-IV.
Wreckless certainly doesn't need anyone to back him up, but I'd like to stress for everyone that will read this thread: doing a few burnouts on a stock motor/transmission and getting away with not rolling the second gear sprag does NOT mean you should. It is a known weak point, documented by Supra owners and transmission builders all across the country. There is NO POINT in doing a burnout and having it shift into second gear. Doesn't matter if it looks or sounds cool, just stick to first.
BUZ, your last post bumped a 6 year thread to quote some information you found on wikipedia. You're 0 for 2 now...come on.
Is someone able to post screenshots or cal files for the Auto Box settings (30-6100 V2) with all the bugs ironed out ?
Any assistance would be great.
what kind of bugs are you talking about? the original cal file should be good to control what you have
