I have a 2000 sc300 2jzge non vvti and i’m replacing my auto A340E (35010). Right now i’m ready to reinstall it but i want to be positive the torque converter is seated properly. Does anyone know the measurement for how far in the torque converter should sit, or judging off these pictures does it look right?

 

Hello,

Hard to tell, but I am pretty sure it's supposed to sit Deeper in the Transmission, are you sure you aligned the Splines correctly? If you simply try to spin the Torque Converter in hopes of of it eventually landing in the Spline, it will not work as you are dragging the Shaft along with the Converter as you do so, to install it properly, you have to pull the Converter Out, verify the Spline Positioning inside of the Transmission, and align the Converter before pushing it onto the Shaft, you should feel a pretty distinct feedback once it's seated correctly.

Hope this helps and best of luck!

 

I did align the two notches before putting it in, i’ve felt it distinctly push in 2 notches now. i’ll keep messing with it and see if i can get it in any farther, currently it still has some slack while it’s seated. when it’s in properly will that slack go away?

 

Found the Cross-Section diagram for the A340E Transmission, you can clearly see how much Deeper the Torque Converter sits in the Bell Housing, a clear sign that you missed the Splines. It does take me a fair few tries before I can get it in position, and I don't think that it should have much Slack to it if seated correctly..



Hope this helps and best of luck!

 

I'd say go for it. Pic on the right is from a scrap yard secured with a holder tab. Unfortunately I have not removed my automatic from my car yet otherwise I'd be sure to send a pic as it sits with the converter fully seated inside. Regardless you'll usually be able to tell when it's fully seated in it, will have just a bit of play and you shouldn't really hear much moving around when you move the converter. From personal experience if you have the two notches aligned and made it over the first bit pushing in while spinning helps you get over the second part. Best of luck.

 

What transmission in particular do you have? You listed a W58, which is a Manual Transmission, can you make sure that it is, in fact, A340E?

I found a page from the Service Manual for an A340E that shows the exact measurement from the Converter Mating Plates to the Transmission Bell Housing, check to see what you will get.



One other thing you can do, now that I think about it, is try to Intentionally misalign the Splines and see how far you will get. While not as definitive, if the Converter would stick out even more, it would be safe to assume that the Converter is all the way in.

Hope this helps and best of luck!

 

Seating the TQ is pretty easy except it requires the bellhousing to be facing straight up. When it is rotate and lift/drop the TQ at the same time until it's at the lowest point, you'll know. Your does look fully seated however.

 

Arsenii you’re right I had the wrong transmission listed, it is a A340E 🤦‍♂️ My torque converter is definitely not pushed in as much as the one on your diagram but i connected it back to the engine last night and it required no forcing it on or anything and it seated really easily. The flex plate was about 1/8 of an inch from the torque converter bolts and pulled the torque converter toward the flex plate slightly so it should be seated properly. The torque converter only pushed in two notches but I had gone at it for about 45 minutes lining up the notches then removing and installing it, it seems like the farthest it will go in is two notches. Now I have the car put back together and i took it for a quick test drive and didn’t hear and strange noises or have any weird shifts so as of now it seems fine. My final step is tuning the TCM, i have no experience with tuning so if you guys have any advice for me that would be appreciated. thanks for your time so far

 

It's the Pilot on the end of the Converter that threw me off, it's usually not supposed to stick out by that much, so I thought it would be better to play it safe. That said, if the transmission went in smoothly, you indeed have nothing to worry about, at least regarding the Torque Converter that is..

Either way, thanks for the update!
