My transmission has been slipping. I was hoping it would make it to springtime but no dice, third gear is gone. It goes through first, then second then it's in neutral. If I can get it up to highway speed in second then shift to drive, fourth gear holds-until it wants to down shift to third.
I went to see Bubba my Chevy parts guy with the part number for the "correct" unit for my truck. There was one in the warehouse at a discounted price but we just missed it, somebody else called for it an hour earlier.
They had 2004 units in stock-but it has a different part number.
We determined everything was the same-including the all important wiring harness/plug. Only the torque converter was different but we researched it and found they freely interchange. These transmissions are swappable from like 1999 through 2004. Starting in 2005, they had input speed sensors added.
I ordered the 2004 unit. It'll be on the counter tomorrow, no core charge, no shipping the core across the planet, I just gotta get it back when the swap is done.
I'm adding an external cooler with -6 AN lines and using Royal Purple Max ATF. I'm NOT a RP fan but my race transmission shop uses it and they say it foams the least. Good enough for me. 5 gallon jug on amazon is $211.00 with shipping-which is a VERY good price. I need it for the Trans Am too, it's soon gonna get it's engine & tranny installed.
I'm also replacing the leaky rear main seal and tossing on a B&M flex plate with ARP bolts.
