1968 camaro 4 speed conversion and transmission is hard to go into gears once car is hot
I am newer to the forum at posting but not really with cars in general. I have a 1968 camaro that was originally a 327ci. motor with a 3 speed transmission. I did a swap and changed the gear to a 3.73 from a 3.08 and also put in a used 4 speed muncie, with a 3 finger brand new zoom clutch. The clutch seems like i went out to the end as far as adjustments go b/c i am right at the end of the adjustment rod. But after doing the swap I too the car for a ride and it goes into everygear fine, when the car is dead cold. Then as soon as it gets a little hot the trans doesnt want to go into reverse without a grind. When the car gets a little hotter like in a bit of traffic or continuous stopping then the transmission gets nearly impossible to get into almost every gear. Especially in first it almost feels stuck, and won't go in at all.
I know you guys really know ur stuff here on this website so I wanted to ask you if you have any suggesstions. I heard from a friend that it may be the fluid that is a bit to heavy a weight and when it gets hot it gets a bit thicker and that is whats causing it to get hard to shift. Also I heard it may be the three finger clutch that I should just get rid of that one and get a diaphram clutch b/c they are rated up to 500+ hp and that is plenty sufficent to my nearly stock engine. I heard that should be the biggest help.
I would really appreciate your comments and help, or at least suggestions. Also if you have had a similar experience and what you did to fix it.
I appreciate all of your help.
