Hey guys,
I recently rebuilt and reinstalled my transfer case. While I was at it I decided to tackle trying to fix some leaks on my 1975 C4. I replaced the pan with a deeper B&N cast aluminum pan, replaced the seal/filter. It still was leaking like a sieve. I looked closer and found it was leaking at the vacuum modulator. It is the press in style. I bought another ( green stripe), replaced it, and it still leaked. I removed it and put a little permagasket around it and...... it still leaked. So I removed it today and holy smokes did I find a mess. There are some massive cracks running through the insertion site for the vacuum modulator. Maybe from overtightening the bolts on the pan? I am thinking I probably did not do it with the replacement because it has been leaking pretty heavily for a while. Either way its leaking now to the point that I cant really even drive it. Is there any type of fix that does not involve removing the transmission? A sleeve possibly? JB Weld? Anything?
Thanks in advance for any and all help
