[CHEVROLADE]

Ok Guys This Is Weird But This Morning I Dropped Off My Grill And Hood At My Local Painter To Get Painted And Problems Started.
So It Was Like 40 Degrees With No Hood And Grill And Forced Induction ,i Had To Get On It,it Ran Like A Beast,but Then I Noticed While Cruising With ,just Coasting(not On The Gas) The Rpms Start Jumping From 500 To 700 Like It Wants To Shut Off And W/b Is Lean -till I Get On Gas,but Its Constantly Lean Just Coasting,sounds Like Its Cammed-ha
Now The Headache-in Drive My Tranny Shifts From First Gear To Third,no Second Gear!!so I Manually Shift It From First To Second ,it Just Stays In First.but it will get 3rd and fourth.
I Have A Tranny Cooler,2nd Gear Servo Just Put In Not To Long Ago.im even thinking of putting the stock servo to see,but who knows it was running fine before.
I Dont Know Wtf It Is,but I Have A Big Headache.its wierd ,it started when i took the front end off-lol
Any Suggestions Would Be Appreciated-

Thanks-zach

Sounds like you have the same problem I have! My truck will just go from 1st to 3rd. It will go to 2nd but all that happens is the motor revs.(My 2nd gear is screwed) Sounds like a fried apply band to me though? But what do I know.

man this situation sux,mine does the same sh1t!!ill go 70 mph in 3rd,and ill floor it,and it drops to second gear but only it redlines,it dont move!!ill manually shift it from lo 1 it goes,then i shift to second and it stays in low 1.but when i go to third it shifts fine,to od as well.

Everyone is having problems with there stuff in cold weather

Did the check engine light come on? If you do you do your own tuning try a rewrite. I had a similar problem with the lean condition and an overwrite ended up fixing it. I could never figure out what tripped the computer up but it's definitely not ideal to drive without a hood in the rain.
