but arent they generally known to be much stronger?

 

True but 9 times out of 10, when people break trannies, they arent breaking hardparts. And what the hell good are 5 pinion planets when they start seeing oil starvation problems at 5500 rpms or so?

 

Well they are stronger UNDER 5500, and how often, and for how long are you OVER 5500??

 

Plus its an FLT not a stocker, im sure that makes a difference!

 

True but im pretty sure they use GM planets which (i dont think) have the oil slinging paddles on it like the 4 pinion planets do. I could be wrong. This is what another tranny guy told me a while ago. BTW Im not bashing FLT in any way cuz i am totally happy with my tranny. My converter on the other hand, is a different story.

 

All 16 seconds during my 1/4 mile pass

 

I'm not sure who told you guy's that " 5 pinion planets get starved for oil." Chuck has been testing these since they were released from gm. We only use ac delco 5 pinion planetaries and have never seen this. Maybe the guy who started this rumor was using a jap piece of ****! We throw these away and just laugh. These planets are made from the same materiel as the 4 pinion planets which is cast steel. Also are very cheap and will never be used at FLT. The ac delco 5 pinion planets are made of solid steel. Much stronger than the earlier planets. The only case I have seen with a lube failure had a restricted cooler and the hole gear train was melted. Not the planets fault here at all. I would put up one of the 5 pinion planets against an OE 4 pinion any day!


By the way I like the T-N-T mod although I would probably remove it if I were to rebuild your tranny!

 

well i think the 5 pinion is an over kill i have one just sitting in my shead,i have 2 trans one with a 4 pinion and one with a 5 pinion.and both have ran in the 12.s and both have ran some 1.6s 60' times and no difference.my opinion on the 5 pinion is for cars that are hanging tire their r in my area(town) about 10 guys running 4 pinion and all r low 13.s to mid 12.s and most of them are x-cab and cc trucks and most of them r powerd by a 6.0.

 

slow lets just treat your truck like we did the bronco ! hahaha

 

treat his truck like his neighbor treated that explorer
