Tranny doesnt go into overdrive until 60 mph, is that normal and can it be lowered?

[2kSSLS1]

Just not too happy that overdrive is so high and I wanted to know if it can be lowered. Also, 1st to 2nd is spread out ok, but 2nd to 3rd is kinda quick. Is there a way to spread out the 2nd to 3rd shift and lower the overdrive kickin? Thanks.

Anyone have any suggestions?

after verifying proper tv cable adjustment check to make sure that you only get a wot 2/1 kickdown in manual second at 15 mphour .if it comes in too early suggest a sticking tv valve,tv limit valve ,tv upshift valve,or 3/4 shift valve train problem.make absolutely certain you have a br,bq, cz,or cq valve body with the matching governor or itll never be right.

How do I know if I have proper cable adjustment? Also, I dont understand what you mean by this:

"check to make sure that you only get a wot 2/1 kickdown in manual second at 15 mphour"

As to TV adjustment, perhaps this site will help: (esp. the three part TV101). http://www.tvmadeez.com/

I'll try & translate the Tranese sentence, but I don't speak it too well myself... I think Chris wants you to verify that you don't get a Wide Open Throttle kickdown from second gear to first gear above 15MPH when your gear selector is in "2" (manual second gear, I assume that is "2"- I don't have a GN).

if all shift are on time except for the 3/4 ,clip 2 coils off the 3/4 shift spring.this will lower ther road speed that must be reached to get a 3/4 ratio change.

I have no clue what youre talking about...lol. I had Mike Kurtz at Century Transmission build it. I dont know a thing about trannys.

if you want to fix it we have to either make a decision that you will attempt it yourself as per my instructions ,or go to a trans shop and if they cant get anywhere i will help them.
