ZL1 in the shop Probable trans replacement
I was coming home from work on Tuesday, making a relatively fast shift into 3rd and I heard a grinding noise. Thinking my hand/feet coordination had been off, I tried again at the next light and grinding again. Then I started granny shifting and got a grinding whether I was upshifting or downshifting into 3rd. I am pretty sure the 3rd gear synchros are gone.
The car is at the dealer now and I will probably end up with a new or at least a rebuilt trans. I am going to get the coolant leak on the drivers side block and the rear grinding noise repaired while I am there also. The car is 100% stock, with 15,000 miles on it. I am glad I didn't start modding it yet, that would have just created a hassle with the warranty I'm sure. I'll let everyone know how the whole process goes. |

I'll will definitely update as the work progresses. Thank you for your concern William, so far Armen Chevrolet in Ardmore, PA has done everything right. I test drove with the tech who will be doing the work and he seemed very knowledgeable on the manual transmissions and they hooked me up with a loaner car with minimal hassle.
I searched the forum prior to taking the car in and didn't see many 3rd gear problems, so hopefully I just had a bad part. The only prior symptom I had was not being able to get into 3rd consistently when using no lift shift. It wouldn't grind, it just wouldn't go into gear. Under normal driving, 3rd gear was like butter. |

I saw this problem posted here before. The guy got a new trans. It was a few months back.

Quick update, called the dealer today and they are installing a new transmission. I believe they were originally going to rebuild it, so i don't know what changed their minds, but this works out better. After that they are going to repair the coolant leak and rear end noise. I may have the car back tomorrow. So far so good.

Got you Ninsecgt, thanks. Got the car back Friday morning. Everything seems fine, A touch of gear noise while cold which I attribute to the trans breaking in. They replaced the coolant fitting in the block and performed the rear end fluid service. The dealer told me no break in of the trans required so I guess I am good for 80 MPH+/4000RPM+. Does anybody know any different as far as trans break in? I know when I put the Tremec TKO-600 in my 68 Camaro I had a 500 mile break-in period.

How did this the rebuild work out for you? I noticed that 3rd gear is starting to get hung up on me. If I go from 2nd to 3rd very 10th shift it gets stuck and I have to jostle it over to the right a bit to engage 3rd. I'm calling service tomorrow, but thought I'd ask if ether was anything specific you discussed with the dealer that pushed them to swap the tranny.
Thanks in advance! Christ |
