i just rebuilt 700r4, put it back in got the T.V. cable set like it should be and take it for a test drive. it shift a little soon on the 1-2 shift but it does shift through all the gears pretty good. but my problem is that it will not down shift back to first. it down shifts fine through all the other gears, but will not drop back into first. if i manualy drop it in it will go or if i stop shut it off and restart it will start in first but just driving down the road it will not. i think my line pressure is low but i cant find anything telling me what they should be.
Sound like your TV cable needs some more fine adjustment. Try to tighten it a click or 2. Check pressures for Minimum with TV cable with cable at Idle position. Check for Max pressure with TV cable fully pulled. http://www.tciauto.com/Products/TechInfo/line_pressure.asp
i pulled the valve body back off, and worked it over again. think i found and fixed the 1-2 sticking a little. discovered my pressure switches dont hold pressure, very well. there is 4 total and everything i am reading looks like that pretty much the only one that matters is the 4 gear lock up. should i replace all of them that leak or just get a new 4 gear switch and plug the rest of them. and if so what is the best way to eliminate the excess wire.
it was the 1-2 shift valve sticking and problem solved. local transmission shop tells me that i need those pressure switches for it to work right as far as lock up goes. 60 bucks and problem i think will be all solved. still think it shifts a little early on the 1-2 shift but i think they sell a shift kit to help with that. any kits i should look for and stay away from, any info would be great thanks.
I like the TransGo 700-JR. It's the only one I've used for the TH700's. You'll like it.
