will my 700 r4 be okay if it never locks up due to me switching to carb?

 

Not if you do much driving in O/D.

 

the worse thing about it not locking up is heat. If you install an external trans cooler, you should be fine. If you are still worried about it, you can get a switch that will control the lockup. I think jegs or summit have them for around $150.

 

Yes, and by far the single biggest cause of failure of automatic transmissions is heat.

 

I agree.

But I talked to dana at probuilt. I also talked to someother trans builders, and they all said that as long as you run and external cooler along with the stock cooler it would be ok. It wouldnt be a bad idea to install a temp sensor also.

He could also have the trans converted over to non-lockup.

Trust me, I wouldnt give any of this advice if I hadnt thorougly researched the same question.

 

I'm not disagreeing with anything you said.

 

Didnt try to come across that you were. I guess I thought that I just threw out the info with nothing backing it up. I just get in a hurry trying to help sometimes.

Just thought he would feel better knowing that I had researched the subject.

 

k how bout a th 350 converter? or th 400

 

They won't fit a 700R4.
