They will add value for a trans that has been rebuilt in the last few months. If you spent $2000 on it, will it ad $2000 to the value? No. But it may add $200-$300 to the value.
I know this for a fact - I have worked for the b@stards & did total loss valuations & settled total losses.
I only did that for a couple years as I didn’t want to sell my soul to beelzebub.
Now that I work on the body shop side, we do all of the total loss valuations for the insurance companies that we are a direct repair shop for. Done thousands of them.
Fred, if you want to, pm me tomorrow
