As the title says....I'm determined to make this Transmission hold this amount of power. I know most guru's don't like the 5R55E and probably think it's a lost cause. The problem I have is I'm pushing this Transmission to the limits without a problem. James has pushed this Transmission to the limit and started to get some slip. This was at higher boost levels from his turbo. Was it because of the mileage? What exactly are the limits? Has anyone ever broken this Transmission with decent power? (I’m not talking about your normal failures with a stock engine - I'm talking, got on it hard and it came a part) The 55 in the name means 550 LBS of torque, correct? Then why can't this Transmission hold that and who has really found this out? I've searched and searched (many forums) and there is still no solid proof that the failure was the Transmission itself. In fact, I've seen threads where someone would swap to another Transmission (a so called bullet proof Transmission) and self destruct that one as well. That tells me a driver variable was in place and the info about a bad 5r55e Trans get's thrown out the window with that.
From my knowledge learned in this forum, the 5R55E technical design is not as good as some of the newer trannies, like the 5R55s or w. If it were, there wouldn’t' be a need for the S or W. So you see my delimia here?
Here is my plan.
1) Get a Transmission cooler with a fan - I'm thinking about this one - http://store.summitracing.com/partdetail.asp?autofilter=1&part=BMM%2D70298&N=700+0&autoview=sku
2) Deep Tranny pan & tranny temp gauge. *note - tranny pan requires a 4X4 filter.
Here is the pan I purchased -http://www.yourcovers.com/tp_9614_2.shtml
Here are actual pictures of the cover. This is a very solid pan; very heavy duty construction. -http://www.explorerforum.com/forums/showpost.php?p=2013116&postcount=36
and gauge purchased - http://store.summitracing.com/partdetail.asp?autofilter=1&part=ATM%2D4357&N=700+115&autoview=sku
3) Do the shift correction kits on the Transmission, OR
4) Possible get a rebuilt valve body? There is a place online http://www.phoenixhardparts.com/browseproducts/5R55E-Towing-VB.HTML that offers a towing valve body upgrade. - What do you think about this one?
5) Work on the the tranny tune. The goal here is to keep the torque convertor locked as much as possible to reduce heat and reduce the torque on shifts.
Lastly – Check and check and check….Service. Service. Service.
- Adjust bands every 10-15K - http://www.explorerforum.com/forums/showthread.php?t=158160&highlight=5r55e+band+adjustment
- Change fluid every 10-15K
The bottom line is, I’m fighting to not have to swap transmissions. If I have to, then I do but I’m not completely sold the 5R55E can’t handle the 450 MAX HP and 550 Torque. I really do not attend to make this much power so I’m just setting some fluff.
suggestions are welcome.
