Allright, I am just not getting it. I have a TH400 and NP208 setup. When I try to drive in 2-HI or 4-HI the motor bogs and dies on me, but in 4-LO I don't have a problem at all tranny shifts fine, but takes alot of gas in reverse. Is it the tranny or the transfercase? Any ideas. Tranny fluid is full and so is the T-case. Help!! Don't want to yank anything if I don't have to. Also Could the torque converter have anything to do with the problem?:confused:

not an expert, but I'd have to say it's the tranny because you stated it does it in 2Hi as well...

Has the vehicle sat for a long period of time, and now this happend?? If so then I would say you have some stuck or hanging valve in the VB. If it is some thing that has been going on for a while. ie: sliping, shifting erratic, or harsh, I would say you have a direct clutch issue. And or center support issue.

I've got a 350 with 305 heads. I istalled a Edelbrock Performer Kit. 1406 Carb, Performer Intake, Cam, and Lifters. Could the Torque Converter make this problem?
