grinding transmission

It might grind less if you go to neutral,wait a second,then flip to high,bump rpm where you need then go in gear.

 

The friction material is worn from your high side synchronizer ring. It will run this way for thousands of miles but the downside is you are damaging the auxiliary drive gear in the process which is a couple hundred dollar part. If your transmission is high mileage you should consider getting g the whole thing gone through rather than the back box of you depend on this truck to make a living. Too many people have this issue as well as others in the front box but neglect to fix the whole thing and it can end up costing you more in downtime than it would to have gone through the whole thing in the beginning. The cost difference is 12-1500 for the back box vs 3450 for the whole thing with a warranty.

 

Holy crap!
That's crazy for just back end.
Should of been $2000 tops. Parts and labour to do the back end.
You could of had a compleat exchange reman installed for the price you just paid.
Oh well, live & learn . Glad it's fixed.

 

We charge 1500 for the back box repair 4 hours labor at 92.50 p/hr 370.00 to r&r the box plus oil 165.00 and miscellaneous shop fee of 45.00 so 2080.00 + tax with one year unlimited mileage warranty

 

So there ya go. Was not to far off. Lol

 

If you got the estimate in writing,check the state law. Some states they can only charge a certain percentage over the estimate. Prevents shops from bending you over.

 

If they informed you of the extra cost,before they continued,then not much you can do. But depending on your state law,if they just went ahead without notifying you,they get to eat part of the bill.
I live in Nc,here written estimates are capped at 10% without consent.
