Short story long.
Have a buddy running a w4a33 auto.
He’s been through three pumps in just under 6 months.
Car went 300 miles and then lost the pump. Replaced the pump and then made it 20+ miles. Then that pump broke.
By the third time, he asked for my help as I’ve rebuilt a handful of autos and said I wasn’t the best at it but I’ll take a look and help him figure it out.
So we replaced the pump for a third time, did a quick inspection of some of the internals. It all checked out and within spec. Also, replaced the torque converter. Installed transmission and the first thing I noticed after installled was the 1/2+ gap between torque converter to flexplate(kiggly). So I thought “bingo” the gaps to great so when he tightens the converter to flexplate. It’s disengage the converter from the pump. So, I help him shim it between 1/8-3/16, which is a spec that seems to blanket most applications. Never did find a spec for this trans/engine combo.
However, we got it all back together, added fluid. He pulled it a whole 5’ and bam! There goes pump #3.
We are both a bit lost as to what could be blowing the pumps up..... any help or guidance at this point would be appreciate. Thank you!
