Torque Converter


Recommended Posts

Hi All,

MY03 Boxster 2.7L

Tiptronic G40

Transmission Type A8605 (ZF 5HP19FL)

DME7.8

Torque converter been rebuild the 1st time after a bushing spun out. Torque converter rebulid was not perfect

when it came to the weld of the hub to the body, started a small leak that was not noticable at all until transmission

lost enough ATF to cause a relatively big leak that lead to taking transmission out and rebuild the Torque Converter

again.

the 2nd rebulid I suspect and I need to verify is that the Hub is about 2 mm shorter that what it suppose to be

I backup my claim for the reason below see pix

connected to each other looks like this

so if you look at the arrow the dark area represents how much engagement between the tc hub and front pump gear

and it suppose to be all the way as shown in the 2nd pix lower right

next pix shows how front pump and tc hub mated

the gap did something that created the uneven wear of bushing see pix below

hub length according to the website below is suppose to be 44.65mm see pix

Anyone by any chance have or can direct me to get more technical information about

the Torque Converter specs.

I took the converter to a local shop called PDQ transmission parts that does rebulid TC

all they did is open the TC, change whatever needs to be changed inside (not sure if they really did) smooth out the hub and stamp the tc with ZF 68

and paint TC with black paint, they could not take the old paint off (san jose job paint). that cost me $300.00.

but when I took the TC to san jose shop they indicated that it is a ZF 75 and written by a marker as ZF 75.

PDQ claims that these codes are not unanimous between rebuliders

anyone rebulider can coded anyway they want to. I have not contacted PDQ yet since I found out about front pump gear.

what code is given by ZF to the torque converter (ZF 75 vs ZF 68 .. etc) , are these codes really given by ZF !!!

any help is greatly appreciated.. would like to fix the problem once and for all.
