Last Night I was at the track and I went to launch and I heard a loud pop. The car stopped moving and I heard a clunking sound in my rearend so I limped it home and I changed my rearend. I then went to test drive it and the car still wouldn't move so I dropped it down to 1st and the car drove fine until I shifted into second and the rpms just went up but the car wasn't moving any faster. I then shifted to 3rd and the same thing happened. then I put it in drive and it engaged again but it won't go into overdrive. I have a 4L60E with a 3800 TCI, Trans go Shift kit, and B&M cooler. I check the fluid and it was at the proper level but it had a bit of a burnt smell to it. Any ideas what the problem is?

 

sounds like the reaction shell (sunshell) broke. one of the weak parts. basically, the trans comes out.

 

How difficult is it to install a rebuid kit in a 4l60e? Does it require any speciality tools? I installed my torque converter and Trans go shift kit so I have some knowledge of the tranny.

 

Well you need a new sunshell AND a rebuild. The sunshell is probably about as much as a FULL rebuild kit, so your looking at about $600 atleast to fix.

 

Fromwhat I have read a broken sunshell means I have no reverse no 2nd and no 4th. I have reverse and no 3rd. So could it be something else.
