I used to have fun doing that all the time. One day at a stop light I floored it and for whatever reason, waited a little longer to slide it up into 2nd. When I did, I heard a real nasty bang underneath the car. I didnt do any major damage that I could tell for sure at the time. It shifted fine and was smooth afterward. This happened about 5 months ago.
About 1 month ago, I started getting a "clunk" when I put it in reverse. Sometimes it happens when it downshifts into 2nd from 3rd. Again, no problems shifting. It shifts great, just a "knock" sound as described above. I am not a mechanic obviously. BUT, I stopped doing that because in my opinion, that somehow caused it. Even though it started a knock months later. Im taking it into the tranny guys on Wednesday and they are going to replace the UJOINTS and the Swivel Flange at the back. I hope to God that solves the knock. Just thought Id share this because I was always shifting around my auto. I won't do it anymore no matter how much faster it makes my launches. I will wait until I can afford a shift kit ![]() Just my 2 cents... |

Have fun "slip" shifting! You can also have fun paying for a tranny rebuild! They tell you how to do that in the manual for circumstances like driving up or down a steep hill. Also for driving on different road surfaces or for towing (which believe it or not, Ive seen people towing ski-doos down here behind a Mustang). Im not saying that doing it on occasion will hurt anything but IMO, doing it everyday will cause issues. |

I had a different opinion on this about 6 months ago or so. I said the same thing.."if the manual says its OK , than it should be". Some guys on this site told me I shouldnt and I did it anyway. Like a moron, I might have caused a problem. My car should not have made that nasty metallic clanking sound when I slipped it. Well, I'll know the damage Wednesday and maybe know for sure if thats whats causing my knock now.

Please don't mess with low 1 and 2 gears. Shifting like that is so bad on the tranny. I'm glad someone else finally ran into this problem to. when I put it into reverse in my car theres a small clunking noise then it goes in. When I come to a stop I can hear and feel the car downshift hard into first as it makes a snapping noise. And my 3rd to second downshift sometimes feels like me doing 40 and shutting over drive off. This is all in drive btw. If this is a similar to your story ja002gl then I doubt u joints are ganna fix it. I thought that was the problem before but im allmost posative both our trannys are beat.
I learned not to do it anymore. I use to do it cause I though it made my car faster... it really just gives better throttle response. So in the end don't do it cause now I'm spray on a bad tranny and I'm waiting for it to go out so I can put my 100 shot on but I don't thing 75 is ganna do it.

well..in my opinion...i woudnt do it...simply because the compression in a aauto compairedto a manual tranny r really low...thats y they offer that SHITKIT that GF was always talking about(BTW WHAT HAPPENED TO HIM) the shift kit will improve the quality and compressioin in the auto tranny and give it the extra power behinde its gears to shit BETTER then a manual..pluse it looks way cooler 2!

Well its fine if you have the shift kit and the shifter... but for the stock tranny just leave it in drive.

get an xcal2 and adjust your shift points
as for shifting manually in your auto my cousin did this in his car(not a mustang but will happen anyway) he thought it was faster...i proved him wrong. he still did it. then 2 weeks later he tells me when hes in D his car makes a clunk or a hard shift. that like tosses you back n forth.. i told him it was from his manual shifting in an automatic car he still did it...his tranny went...paid a shit ton for it. your tranny will get worse in the higher gears then just totally screw up

Re: Sport shifting an auto
the reason it starts harder in first is cuz the converter is already ready to go and locked for first gear cuz it knows thats the only gear it will be in cuz your selected it. just try not to over rev and hang in the high rpm to much not good for the engine |

My transmission might not be close to done... but its clunky, and downshifts hard, and I hate listning to it. Someone should sticky this cause every v6 guy with an auto trys it, and only a few learn from it.
