that is good, I also sent an email, as I needed to get my info for updates and probably asked for the same info as well.

 

ok here is what they said in the second e-mail.

"We were referring to the fact that the Maximum gearbox torque rating for the MN5 is 325 lf-ft. We are forwarding this information on to Bill but in your original email you asked 3 questions and 2 were if the transmissions held up in our testing. These cars are daily driven and they are driven hard, we have gone full throttle from a stop for testing purposes and the transmissions have been fine. We haven’t had any issues at this time that is why we have released the tune for the auto trans applications.

Also when we referred to ‘treat the trans right’ it was referring to standard rule of thumb transmission care I.E coming to a complete stop before shifting from reverse to drive, no revving in neutral and shifting to drive, no brake torques ect… Even though this trans is a ‘fill for life’ trans with the added power it would be wise to maintain the fluid to make sure if a change is needed it can be done."

 

encouraging response, but still on the input shaft rating of lower torque, so I would assume that they would feel that is not that much of a problem as was thought originally. I may do a WOT soon, we shall see..
good work agentsmith23

 

Here is a thought on the torque handling issue...

Without drag radials and neutral drop launches (LOL - in Hanns email reply) I wonder how much Torque related to the input shaft can really be applied to the ground w/o wheel spin on the stock rubber?

Also having the T/C off might actually be better for the trans as the brakes cannot load the trans. With foot controlled wheel spin just maybe the trans could live a while.

I would like to check into the trans cooler idea. It might require the pan to be tapped and a separate pump be installed to circulate the fluid through a cooler if there are no lines available to take fluid from.

Great thread.

 

thanks......the trans cooler may be something to think about in the future. but I think that we are going to be alright, it seems that Hahn did a lot of testing form their emails in the above posts, and they did wait to release the tune for the auto.....so I am sure they were satisfied with the results

 

there is none
reason being getting ready to go down to the Jersey shore
will be there for the next week, although I don't have a laptop, the place where we are staying has computers available with the internet
so I will be on whenever I can, hopefully someone else may purchase the tune by then
We are taking the SS, so I will get more highway time on the road, and some more mpg readings. Might even have a few high-speed bursts......

 

So far so good it seems. I think the only part everyone is concerned with is the transmission and how much they can take. It's like the F Bodys with 10 inch rears. (

 

BIG HUGE THANKS! I have been toying with the idea of buying the tune? I really appreciate reading your thread as it is making my wallet burn, with your updates. Curious question, if I were to go with all Hann has to offer, does the tune take into account IC and Piping, exhaust, etc.? Do you have any plans to upgrade these items to your car?.......

PS I think we are all awaiting a WOT report.....

 

i am having major problems here on vaca, with their computer system, probably won't be able to post until I return Friday

figured out I hope what is needed to post here, I have to post to one response at a time.
Computers...........I miss mine!!!!

 

I understand what you are saying, that is a major concern. All I can say at this time, is that I think we will be hearing some encouraging news from Hahn in the near future concerning this issue. again the tune is wild....
