Default Help- did I crush my trans pump ?

So I'm in the process of installing a new converter , I thought I had the converter seated right but apparently it wasn't . I didn't notice until I started tightening down the bell housiing, The converter was touching the flex plate. And the bell housing was almost touching is what scares me ..

I immediately took it apart and got the final seat on the converter .

I plan on finishing this weekend , but now I'm nervous , did I crush the pump or is there a chance it's ok ?

Will I be able to logg the actual pressures or anything once it's together ?

You can absolutely log the pressure and you should. I would guess its good though

I swear the converter clicked in 3 times but I guess not .
I was cranking on the bell housing bolts pretty good honestly . It was almost matted up to the motor before I noticed the tension on the bolts wasn't right and then noticed the converter touching .


Question now is , do I finish putting the exhaust on and drive it or cut my loses now and drop the thing back out again.

What are my odds ?

I would think that you would crack the bell housing before you damaged anything else as long as you didn't start it up like that.

Good chance you cracked the pump rotor.
It's weaker than the bellhousing.
I would want to replace the pump rotor even if it has no visible damage.
I've seen the end results of this scenario too many times.

I agree, a little extra labor right now and a rotor - but the risk is not worth it. If it is cracked then it will then need a whole new pump, clean out the transmission and converter will need a new hub.

Lol.... I wasn't picturing the TC hub jammed against the tabs. I do have first hand knowledge how much deflection it takes for a bellhousing flange to crack though.
