i have an 89 iroc with a 350 in it, and 700r4 transmission, and about a couple of months ago one day my transmission wouldnt shift out of 2nd gear now it does this onc every other month, usually i just drive to the end of my street and shut it off for about a minute and then its fine, i have already had a full transmission service done it like new fluidand filter, and when it does, when you first go to put it in gear it jerks real hard! does anybody know what the problem could be???

 

who did the service? you might want to get the trans rebuilt

 

Mine shifts kinda hard when I put it into gear..

When I go to WOT, it slams into 2nd and 3rd.. hate 4th (OD)..

Pretty sure that's how it should be..

But anyway, if it's sticking in 2nd.. sounds like you need a rebuild..
