Re: 700r4 lost 2nd gear
when the 700r4 goes south, gears just dissapear! your first gears is next, the 3-4 and reverse.
what year transmission are you dealing with? pre 89?
check your fluid, i bet its black and burnt, probably got hot at some point. is you get it rebuilt and it is a pre 89 trans, make sure they upgrade the sunshell inside the transmisssion as they are famous for breaking apart into a million pieces!

Re: 700r4 lost 2nd gear
I know that it is a multi-stage servo that activates 2nd and 4th. If the band is worn Im told I might be able to patch the trans with a longer servo pin to apply the band in 2nd gear.
Ive also been told I may have a damaged 2nd gear accumilator. Any thoughts on either of these possible solutions?

Re: 700r4 lost 2nd gear
I do my best 
But really its time for a new trans or a rebuild.
Get one of them 0 intrest for yr low limit CC and get a trans.
ALso flip for a shift kit n higher stall TC.
Well worth it, Im happy to send Discover $35 a month for the Trans they bought me.

Re: 700r4 lost 2nd gear
Good idea about the cc, never thought about it that way. So thanks. Also, Im shopping around and they're about $900 to buy, and then some pretty good coin for shipping. Yeah, I guess your right, I probably should just take it like a man and get a new one. Still tempted to search the junk yards, but I guess you get what you pay for. Ive rebuilt a turbo 350 before and a toyota 5 spd, just kinda intimidated by the 700R4. The 350 sat on my kitchen table for 2 months, till I could find the time to get it done, but was fairly simple. Anyways, thanks for your help Gumby

Re: 700r4 lost 2nd gear
I thought maybe the band broke too, but I have all other gears including overdrive which shares a band with 2nd... its 0 degrees here with a -2 windchill, so Im not thinking I want to drop the pan right now, will maybe try for wed-thurs if it warms up a bit. Thanks for your info... and what are you asking for the trans?
