Hi there, Luke here from Down Under.

After much research and some trepidation about doing this job, I attempted to drain and fill my 2003 2UZFe Cruiser equipped with the 5 speed A750F with dipstick.

In short, I followed the dipstick procedure recommended by Toyota after I called them just to double check about fluid level check temps.

They suggested to just use the dipstick level as a guide when COLD and also when HOT (at operating temperature??)

I may have overfilled after draining out 2.3 litres (warm fluid)???

I put back in the same amount and ran it through the transmission Park > Low > Park - 3 x through.

I checked the dipstick level and it sat just above the top mark on COLD.

I then went out driving to bring vehicle to operating temps to check fluid level at HOT on the dipstick...

At approximately 80 km/hr I accelerated to get the transmission to change back to 4th gear AND then complete loss of power.

Nothing...

The A/T temp warning, battery light & Engine warning lights came on and the car stopped.

No power steering, no acceleration...

Limp mode I guess.

Had to get it towed home.

I've never had a problem with this car.

I did have techstream attached via OBD at various times to check ATF temp LIVE.

Once home. I ran techstream Health Check diagnostics and got an ABS DTC C1340 and 2 x calibration codes under ENGINE & ECT 36031100 & 56011300.

The vehicle will start but then stalls after a few seconds.

I'm gutted.

I would be most grateful if anyone could shed some light on my dilemma


PS: I have highlighted things which I did which could have influenced the operation of the vehicle.

But would make it lose all power and stall?


Thanking you in advance.


Cheers Luke

Maybe you put tranny fluid in the engine ?
 
Maybe post some pictures of the engine bay showing us the areas you’ve been working and some of the vacuum lines in these areas.
