Hello everyone! I am new to this forum and am wondering if anyone can help me out with a problem on my 06 srt quad. I purchased this truck 6 months ago from a person who had a venom 1000 twin turbo upgrade from hennessey. Unfortunately since I've had it I have run into nothing but issues. I've called hennessey numerous times and all they could do for me is verify that they did do work to the truck, short of that they won't return calls and refuse to help me resolve issues with the truck. I've spent alot of money on a truck built by them and have been really dissapointed with their customer service. With that being said I seem to be have transmission problems now after spending 12k on a bad mannifold design set up! My transmission is going into drive but when it shifts into second gear it just revs like it's slipping. Can anyone help me out. I've only been able to drive the truck a total of two weeks in the period I've owned it! I had the filter and two sensors changed in the tranny to see if that would fix it and it still does it! No metal at all was in the fluid just your normal grime you would normally encounter.
