stroker007 · #1 (**permalink**) 09-08-2012, 07:29 PM

i have been running the kem 345 tune for about 1k now, have not beat on it by any means. i get on it every now and then but nothing crazy. truck has 79k miles on it. first gear is a little firm which is ok, but 2nd and 3rd gear is terrible. it feels like they slip into gear and it jerks real bad. the other day i was taking off and when it got to 2nd gear it wouldnt go into gear i gave some throttle and nothing and i hesitated then gave a little more and it clunked into gear. any one know whats going on? truck shifted perfect before the tune.

Mine clunks the 2-3 shift pretty harsh...mike wont get back with me for the fix either. Im pretty pissed cant wait to get someone elses tunes for my H&S and throw this card in the garbage.

had the same thing happen. bought the sd card because of good things i heard about mike. 2-3 shift was terrible, mike wasnt helpful at first but eventually seent me a modified tune. While trying to reprogram I accidentally cleared SD card. Called mike and was told to send him 50 bucks for a new card= end of kem tunes for me. Got 300hd and could not be happier. Truck has great power, mileage, throttle response, and awesome shifting.

no he never said why this was happening he said it was normal. but shifting like this is not normal.

yea i want to upload the hd300 tune but my computer wont do it for some reason. how was the power between the 2?

the slipping happened again today. was going bout 25 mph and went to give it some gas and it couldnt find the gear and reved up went to try again and did the same thing. finally the third time it slammed into gear and through a code. it put a wrench on the screen. any bodys before do this?

there is so many different things that can cause this.

Its definitely a tuning issue though, you're going to end up wasting clutches
