Race car only......Th350 with B&M shift kit. Under normal pit driving and on the return lane, I have all 3 gears. Under full throttle I am not seeing 3rd gear. Tried it manually shifting and also leaving it in drive under full throttle.............(no 3rd). There is "NO" kick down cable hooked up. Vacuum module "is" hooked up to intake port vacuum. Let me know what you think. Thanks.

I have something similar, I have to let off for the 2-3 shift when going wot. Normal driving is fine in all gears.
