Two transmissions from PATC http://www.transmissioncenter.net/hi...00r4.htm#Parts
and not one works as it should.
n°1. 700raptor level 3 with a 2000rpm #5X power raptor lock-up converter.
Comes with black powder coat.
-gears banged nasty, shifting up and down since day 1 and little blackish trash could be cleaned of the magnetisized dipstick.
-after a 5 miles cruise it did not whant to upshift anymore, found some tiny metal chips on the dipstick.
Kerry from PATC told me its some trash from the previous transmission that was stuck in the radiator.
Wich I though is possible since I only used compressed air to clean the cooler lines.
-the 2000rpm TC would stall only at around 2600rpm.
Kerry: "Torque converter math is figured on an engine making 250 torque at 2500 RPM. Thanks, Kerry"
That sounded right to me, my engine should be putting around 350 tq to the wheels.
Issues started immediately.
I refreshed the transimission oil and it turned out shifting again.
I hated that transmission, banging shifts, stupid high stall for normal driving with 4th lock up only.
n°2. 700raptor level 3 with a 1600rpm #2 super street raptor converter with stock lock-up and corvette servo's for smoother shifts.
With no paint as I requested.
I installed the Derale automatic transmission filter kit, for extra safety.
-gears bang nasty shifting from P or N to gear, 2-3 shift bang and little blackish trash could be cleaned of the magnetisized dipstick since day 1.
-manual 1-2-D shift control does not work, it stays in 1st.
-after 10 miles highway the transmission was acting wrong and the transmission fluid was toast.
Total miles around 20.
I refreshed the fluid and drove the car to its storage. It makes a silent jet-plane sound shifting.
I am wery disappointed, pay'd big $$$$ and still no resonable working transmission.
Any ideas what to do? I'm thinking of rebuilding the stock 700r4 my self.
