I am dropping out my Series 1 3800/4T60e swap that is in my 87 GT and installing a 2004 Series 3/4T65e (HD)

I am pretty sure my Purple Reign mounts will work.
Are there any other brackets that need changing?
What axles will work?

Mounts will most likely not work, but it depends which style you have.

The pass side axle you have will need to have the inner tripot replaced with the GrandPrix GTP inner (not autozone).

Cooler lines will not work. 04 uses push lock style and you cant swap the fittings due to the checkball being external (in the fitting) in the 04 trans.

PR's thread in the Mall states they should work with the 4t60, 4t60e, 4t65e and 4t65hd

As long as your 4T65E has the bosses on the trunk side tranny mount they will work but I doubt your tranny will have them, as mentioned the pass inner needs to be a GTP or Regal GS one and the driver's inner may also have to be replaced with a GP inner as most of the 4T60E trannies I have seen had a different inner on the driver's side.

What they are saying is there is a transmission change in the 4T65E-HD in the later models for the way the mount is setup.

Earlier model tansmissions use a trunk mount like this (and the Purple Reign will work if your trans looks like this)


And the later models used one like this


If you have the later transmission then you will need to order the mount from West Coast Fiero: http://www.westcoastfiero.c..._mount_brackets.html

The firewall side bracket is the same

Isn't it strange that after a bombing, everyone blames the bomber, his upbringing, his environment, his culture, his mental state but … after a shooting, the problem is the gun?
