Alright guys I just want to share my experience with the 4L60E to th400 swap.
I already had my 4l60e built about five years ago with top-notch parts supposably able to handle 650tq. But for the past two years I have been pushing it pretty hard. I can't complain it did last me. But I always told myself when it came time that I would swap to a th400. Because I couldn't bring myself to spend another 1500 on the 4L60e just for it to go out on me. The th400 are bulletproof if built correctly.
This car's not my daily so I don't mind not having to Overdrive. This is the one things you need to know going in. I probably would not recommend this for someone that daily's their car.
These are the parts I got as followed for the swap.
FTI th400 with rmvb (shout out to the guys at FTI) trans came with 6an male fittings already on the cooler output lines.
FTI Sr 4k stall with pilot extension ( converter comes with 3 sets of bolt holes)
Hurst pistol grip shifter
Sphon th400 adapter kit
M6 crossmember
6an male to 5/16 Hardline adapter fittings for the stock cooler lines
Steel braided nylon hose
2 45 degree hose to 6an female fitting
2 straight hose to 6an female fitting
To mount the shifter to the stock location I bought the bracket from a member on here (JustAfool) I highly recommend his bracket it's top-notch
Just for reference I already had a 98 flexplate which has two sets of bolt holes to bolt converter to the flexplate. The FTI converter bolts up straight to it with the pilot extension.
Just so people know the 98 flexplate does not need a crank spacer all it needs is the pilot extension.
Things I still need to do are connect VSS to the front wheel sensor so my speedometer will work and I know I have to get this adjusted with my tuner. I also need to get my driveshaft shortened and get the th400 yoke put on it. I'm going to try to do that sometime this week.
Here are some pics enjoy. If you have any questions please feel free to ask.
