[QUOTE=magna buff
the important thing with the torgue converter is to make sure the oil pump flats and the torque converter are in place if not you break the oil pump when you retighten the box to the motor

hey buffy, just a questin for when i put the auto back in. now whats this oil pump flats u mention. cos i though the oil pump is on the other end, ie(counter balance chain runs it i thought) so i thought it was next to the timing chain. anyway what am i suposed to do to make sure it dosent brake when im tightening it up. need to elaborate a bit more for me.
cos im not sure on "make sure the oil pump flats and the torque converter are in the right place" what place are they suposed to be?? is there a locating hole or somthing

Always lubricate the converter hub and pilot.

Assemble the converter onto the transmission. Rotate the converter. On most applications you will feel it drop into place. Continue to rotate. A second drop will occur. You must be certain that the converter has been turned more than one full revolution to insure correct positioning on the stator/input/turbine shaft.

Install the bolts that attach the transmission assembly onto the engine. Then tighten the converter drive plate bolts. (Improper technique would allow the drive plate bolt tightening to draw the converter into place. This often mounts the converter ears on top of the pump gears, causing premature failure.) Install the transmission and rotate the converter to ensure proper alignment.


thanks for the info once more:thumbsup: every bit helps. when checking the alignment , im rotating the trans and the engine at the same time? i supose it would have to , just checking. also when i tighten up the bolts that go through the drive plate to the converter, for proper technique the converter should not move ( as in is locked in place other wise if it does move the converter ears might be mounted on the top of the pump?) correct me if im wrong. thnks for the effort uve go to for me:D

thank u kindly:D

Kinda wishing I'd read this before I stuffed my TP autobox. Pic shows the result.

This is the drive from the oil pump on the front of the box.

Now, I have some questions for the gurus on this forum.

I have an auto from a TN. I know the transmission is different, but are the oil pumps interchangeable? Physically, they look very similar, except that the protrusion at the back is longer, the seal rings are located differently, & the back plate is thicker.

Internally, the oil galleries are slightly larger in the TN, & the drive gears are different.

Now, by my way of thinking, if the external differences aren't an issue, then the only thing the internal differences can change is the oil pressure of the transmission. This in turn may upset the operation of the box.

So, the questions I have are:

[1] Are the physical differences a problem when swapping the oil pump from a TN auto to a TP?

[2] If not, do they produce the same oil pressure?

[3] If not, is the different oil pressure a problem?

[4] If the whole idea is an exercise in futility, what do you suggest I do?

Thanx in advance.

magna buff - Just confirming that the TN gears will not fit in the TP pump body - the outer gear is bigger by about 3mm.

With the chipped TP pump, I guess I need to chase a complete TP pump. I will follow up the leads you suggested.

Many thanx

when ready follow that procedure to fit the torque converter location into the flats

You can bet I won't make that mistake again.


make sure you use mitsubishi oil etc etc

Do you mean Mitsubishi branded oil, or Castrol oil for Mitsubishi? I bought Castrol TQM-ST, which says it's for Magna.

Pm answered, I'll see what I can do for ya...:D

I use Mitsubishi trannie fluid....its cheaper :shock:

you can change you avatar now you are not the first to break a pump

Lol - I'll wait until I've got the TP back on the road.

I got it for free - my bro-in-law was working for the scap metal mob in Brisbane & they were crunching about a dozen Magnas a week. I asked him to look out for one with straight panels, as my TN wagon was pretty rusty. He pulled the TP sedan off the crunch line, & it turned out to be better than my wagon.

I had it going for 6 months or so when the daughter cooked it by leaving the rad cap off.

So, head job, rings, bearings, hone, then busted the auto putting it back on. I'll fix that with Ol' Fart's generous help :bowdown: , & hopefully no more dramas.

buffy & ol' fart

Sincere thanks for your help, guys. :bowdown:
