Tranny shifts through all gears just fine. Just when pushing the OD button on the shifter nothing happens. Meaning, pushing the button, the OD will not disengage. The tranny is obviously engaged to shift into overdrive when needed, just no way to take it out of overdrive and keep it out of overdrive via the button on the shifter. So I assume the button is not working correctly? Any thoughts?

A quick question for all of you. My friend has an 86 Dolphin, 22re with A43D auto tranny. His tranny shifts all the way into Overdrive with no problem, but when pushing the overdrive button on the shifter on the steering wheel column to kick the tranny down to 3rd for instance, nothing happens. The tranny just stays in overdrive. So the button on the shifter is useless. Do you think this is a possible fuse issue, overdrive solenoid issue, or something going on with the overdrive button itself. If I remember correctly, no overdrive light ever comes on or off neither.

Lee would you recommend the 4.88 for me in my Dolphin or go with the 4.56. I live in Arizona and am climbing a good amount of hills to get to where I need to go a lot of the time. Plus I run a little bit bigger tires in my rear end. Can't decide which one to go with but I am sure either or will be a lot better than the 4.10.

Yes, it looks like the 3rd member for the V6 should fit right into my rear end with no problem it seems. It being the 10 bolt pattern and all. Just am curious that after I get it in if I'll have issues with the possibly a different spline count than my current 3rd member/axel set up or maybe an issue with my 3rd member right now being a 2 pinion and the V6 model is a 4 pinion? Also, Are the 4 cylinder and V6 3rd members the same length? I ask just to check and see if my drive line will match back up with the new 3rd member or will it possibly be too short or two long? Thanks for all the help.

Hello all! I have a 85 Dolphin. 22re motor. I am also thinking of switching out my third member. I Currently have the 4.10. I Have been back and forth trying to decide between a 4.56 gear ratio or a 4.88. I hear both gear ratios are good reading different forum threads. I run 205r14c tires on the rear axle instead of the common 185r14c so I think the 4.88 will be the better option. My question is, do the 4.88 third members have to be from a 4 cylinder motor also or can options from like the V6 4Runner work. I will just be buying a used 3rd member and am looking at one that is out of a 95 V6 Toyota 4x4 4Runner. If someone could inform me on the guide lines in choosing a third member that would work for my Dolphin that would be great! Thanks for the help!
