Broken Automatic Transmission Pump!

[hughdawgmmkay]

Hi guys,

I was installing my freshly rebuilt engine and made a newbie mistake by forcing the torque converter on :wall:

I thought I had everything lined up but I obviously didn't have the transmission pump notches lined up... so the ring (inside the transmission) that connects to the two notches on the torque converter shaft broke when I tightened the engine to the the tranny.

I am looking for help! I tried to pull off the Transmission Pump plate, but couldn't get it off, or find parts to fix this!

Can someone please help me with advice on what my options are and the best approach to take??

These are the options I know of how to proceede:

Receive direction from someone on the forum on how to remove the Transmission pump plate and fix the broken pump ring

Will need to know where to buy parts too


Pull the tranny and take it to AAMCO
Purchase a rebuilt transmission
Purchase a certified used transmission


Any help would be greatly appreciated!!

so I can get a picture of what happened.

Did you bolt the converter to the flex plate and try to install the engine with torque converter attached to the engine? If so the correct procedure is to install the converter in the transmission and then align the converter bolt holes to the flex plate bolt holes and install the bolts.

Are you saying the flex plate (fly wheel )is damaged. Its hard to tell from the description. If you take the converter out of the equation is the transmission damaged at all? I would think the damage you mention is isolated to the converter but difficult to say. Any pictures?

Hi JPERL!

Thanks for your response! Let me clarify...

I tried to bolt the engine on the tranny with the torque converter already on the engine, and the torque converter broke the gears inside the pump housing :wall:

I did a little more research online and found the internal parts to replace it myself, for a pretty reasonable price. http://parts.germaintoyotaofnaples.com/p/Toyota_1987_VAN/Gear--front-oil-pump-driven/42997471/3532222060.html?partner=googlebase_adwords&kwd=&origin=pla

I've never gotten into transmissions before, but would consider myself pretty knowledgeable mechanically (besides this little incident). I believe now I just need some assistance in figuring out how to remove the pump housing plate so I can get into the transmission to find out what is wrong.

I've attached pictures of what I believe is broken from looking in and poking around.

Any help would be greatly appreciated!

Thanks JPERL! I looked through this and bought all the parts I needed!

To add to the knowledge base here... I figured out how to remove the pump without the $317 SST tool!

Here are the steps I took:

Wrap input shaft in shop rag
C-Clamp on input shaft
Attach one side of ratchet strap to C-Clamp and the other side to front sway bar...then crank!

Also, here is the picture of the damage...hopefully it will teach me and everyone here to research before trying something the first time! :silvervan:
