My 89 Formula when shifting into 2nd is sometimes has a very strong jolt to it. Is this the prolly the bad rearend i belive I have from all the load road noise I get from it accelerating and coasting. I plan on putting the new rear in this week at a shop and wanna know if this should disseapear. Also a nonthirdgen problem on my 92 S10, when I put the truck into park it doesn't go into park and click usually on the first try and sometimes the second. I usually have to slam it kinda hard to have the this click and stay in park, I use the e-brake every time just in case it slips out of park asnd start rolling away. What is causeing this problem also guys?
