Eric Gunkel uses Lucas Transmission Fix in 1983 Chevy k5 Blazer 6.2l diesel

I had a leaky front seal on my tranny so I tried the cheap stuff and it didn’t work so I talked to a friend and was about ready to tear out the tranny and replace the seal. My friend told me about Lucas. So I bought some and put it in and to my surprise it worked and it shifts nice too. Thanks Lucas I’m a believer.
