Topic: Advantages-Disadvantages of valving an automatic

[cmilliron]

Folks,  I am interested in hearing opinions on which way to go when building an automatic transmission for a Land Cruiser...

If I understand this automatic thing (Th350 specifically), it can be built to function fully automatically (like my mother's Delta 88) or the valving can be changed to make it manually shift only...

The FJ40 that I'm building will have to be truely "dual purpose" (highway speeds and granite speeds)...


I intend to teach my wife to climb rocks, thus the auto tranny (she is very hard on clutches even around town)...  I'm having Marlin build me a 4.7 Toybox to slow the whole show down.... ARB's and Longfields in the mix.

Would love to better understand the pro's and con's of each method of automatic tranny setup...

The shift kits I'm familiar with just improove shifting. (crisper, less mushy, better for HD use) You can manually shift an auto already. (L1 L2) I'd do the shift kit and a really big trans fluid cooler.
