I have pulled the 400 auto out of my 70 to be overhauled.It was leaking among other things.The previous owner told me it had some sort of low hold kit[per prev owner].The trans only shifted automaticly up to 2nd.I could shift manually and could feel it shift 3 times but I dont think it actually had 3rd.If it did the difference in rpm between 2-3 was unoticable.If this was a modification was it the valve body?I am asking this because I am going to drop it off for an overhaul and I dont want to get it back with the same problems.I want to be able to give the shop a proper heads up.
thanks Andrew
