47re shifts better when cold

Posted

As the title states. My 47re actually shifts a lot smoother when it’s cold. The shifts can be quite hard once its warmed up especially in light throttle conditions. I’ve tried google but can’t find anyone with a similar issue..

 

I have a suncoast triple disk, dynamic VB, and all the billet stuff. 

 

Other than the trans everything else on the truck is stock.

smoother as in NOT SO HARSH ?  thicker fluid wont flow as fast and can create a cushion for engagement. not always a good thing.

No I’d say the shifts are faster and crisper when it’s cold. Once warmed up the shifts are actually quite hard unless I’m heavy on the throttle then they’re better.

Adjust your throttle valve cable. Make it a bit less pull and this will lighten up more. 

All this stuff has been in for about 1k miles so it’s time to drop the fluid and I’m going to recheck the bands.(clutches and band are new raybestos GPZ) 

 

I was actually thinking that I would tighten the tv cable up a little bit at the same time. The shifts are pretty stacked with light throttle.

Besides exhaust and trans the truck is completely stock 100k miles. 

 

The VB and clutches are from John. I am going to call him just thought maybe it was something obvious I wasn’t getting.

UPDATE

I adjusted the TV cable and got 1-2 and 2-3 pretty good but now I have an OD issue. 

 

For or some reason with light throttle it will try for OD at around 40mph. It’s almoat as if it instantly realizes it’s too early and it will drop back down to third then shortly after back up to OD around 46mph. If I’m heavier (50% plus) on the throttle the shift is much better up around 50mph. 

 

I don’t have an ac noise issue and I did an apps reset and checked that the voltage through it’s range is smooth and linear. 

 

What could make it try it try to grab 4th gear so early? The whole truck shudders when it happens. Seems to be more occurring when it warmed up too
