Nor am I sure that it would solve the problem because some folks online have suggested a worn Tranny output shaft is the real problem.
Anyway, have any of you tried the bypass? I was just going to buy the one from MAF because I don't have the patience right now to source the parts. Below is the link for the MAF bypass.
Is there a better one I should use? I have also heard people say they leave it on even after they fix the seal as an insurance policy. Any thoughts on that?
As always, thanks for everyone’s comments.
After I did my 4 speed conversion, I had this issue also.
I realized I had not put sealant on the tranny output shaft splines when I mated the two, even though I used a new OEM seal.
Instead of paying the bucks for a "kit", I simply went to my local hardware store and got a couple of 1/8 NPT to 1/8 barb fittings, some 1/8 ID tubing, drilled and tapped my fill plugs, stuck the tubing on the barbs and went about my business. That was 4 years ago and all is well. One of these days, whenever I have occasion to unmate the tranny and t-case I'll put some sealant on those splines. In the mean-time, it's all good.
