Trans. shifting goofy once in a while

[86 TR]

Hi guys. I have a issue with my recently rebuilt trans. First off I had it rebuilt by a reputable builder in my area that specializes in turbo buicks. My problem is that it will shift at the correct rpm good firm shifts about 4800-4900 next time it will delay its shift to about 5300-5400. This happens when its at full operating temp.

The trans. has about 2k miles on it and no other problems to mention.

It has a transgo shift kit and a 3000 orange stripe converter .

I would just like to get some input before I take it back to the builder so I don't look like a dumb a@#.

Someone told me possibly there could be something in the valve body to cause this (dirt, etc.)

My tranny guy also put a magnetic filter in line to catch any foreign debris. The trans is BRF throughout.

Speaking from a newbie to the GN TR world, my experience is that every person ive spoke to about these cars, whether they own one or work on them is they are very helpfull and knowledgable. I too feel like a heel sometimes when it comes to these cars, bottom line is call the shop in question about your trans and im sure they wont treat u like an idiot. I had my trans done by Lonnie Diers of Extreme Automatics and i cant say enough about him. WE ALL HAD TO START FROM SOMEWHERE. :wink: GL
