Simplest and most effective thing to do,is to order the Sonnax line-mod valve kit,and a set of Sonnax accumulator springs. It's about $60 for those items,and it's all you really need to do.
The Accumulator springs:
Sonnax Transmission, Torque Converter, Performance, Driveline Parts :: Transmission Specialties :: 36948-18K :: Part Summary
The line mod valve kit:
Sonnax Transmission, Torque Converter, Performance, Driveline Parts :: Transmission Specialties :: 96948-01K :: Part Summary
Both of these items are available online from www.bulkpart.com

Have you ever seen this kit in a truck? Will it give the same shifts as the FTVB? How hard are these to install?
thanks

Do you need any special tools to install either of those kits? and the 96948-01k is for an E40D.

Both are for a 4R100,and I have both installed in my '01 Navigator. Installed them when it had just over 100K miles on it when I was doing a fluid change,and it's got 160K miles on it now. No problems whatsoever,clean crisp shifts without being abusive,and the install was simple. No special tools,no big hassles.

I dunno which pan your trans has. As I understand it,the 4x4's got the deep pan,and the rest got the shallow pan.
