| Hi do you know how much labor is involved to pull a manual transmission out of a 1996 golf. Then put a rebuilt trans. back in it's place thanks | |

I need some help analyzing a problem with the dreaded Tranny that Mazda put into the 626. I have a 4.0 cyl A/T. Currently the car has about 221000 miles on it. It had a tranny change around 90,000 miles and a engine change around 160,000 miles. The problem I have now is after driving for a few minutes it will start to act like it is slipping out of drive and back into gear. I seems like it is going from 3rd to 4th and sometimes staying in third while going 50 mph. Previously the mysterious O/D light would start flashing similar to what happened prior to the first tranny change, which by the way Mazda paid for the tranny and I paid labor as they knew it was a piece of crap tranny  .(dont know for sure if they changed it or replaced something else, I am suspicious) I pulled the code which is a P0708 which is trans range sensor circuit high input. I took the car to to the mechanic (pretty reliable)and they checked the tranny and said they didn't believe it was a tranny change and said they checked connections etc, They said they would recommend changing the computer but weren't confident enough to tell me to spend several hundred dollars and not fix it. I have read about a place you can send the computer and get it re programmed/fixed, but would like to know if there is some way I can check anything prior to doing that. The code tells me it is the trans range sensor input, is there anything other than the computer that can fix this? The RPM gauge has dropped to "0" and bounced back many times, does this have to do with my current problem? Does the tranny on my car have a filter and if it does where is it located? This tranny isn't like others that have a pan you can drop. I have previously changed the fluid. I have been thinking of installing a cooler for the tranny is this advisable? Is there some place a person can go to figure out when you get a code exactly what might fix the problem. I have been thinking of purchasing a manual but not sure if it would contain possible solutions for different codes. I would appreciate any genuine advice you can supply. Thank you Whidbey Rep

i have all the same problems as the above post '97 Mazda 626 Transmission OBDII Code P0708' the only diffence is i own a 2000 mercury mystique i believe it has a mazda tranny in it. this weekend i started having what seems like transmission problems. while driving at about 65 mph car seems to stall and the rpm go up from around 2600 to 5500. then when i take my foot off the gas it seems to catch gears or something like that. then it continues to the point that i stop and let the car sit for several minutes then continue on with no problem for awhile. thought it was bad gas. while driving at low speeds (under 50 mph) i haven't experienced the problem. then last night while sitting in park with the engine idling the 'o/d off' light started flashing for a couple of minute then went out. i drove home don't know what to expect today! any info you can give would be greatly appreciated! thanks :

Drive is the mark you see with a "D" you will need to turn the plastic piece to where the small notch lines up with the line for "D" I marked all my positions prior to removing. Park will line up with the grooved line. You can read this from the computer located in the center console area, but if you want to locate it the range sensor is under your air cleaner. I also bought a tranny cooler and will install tomorrow. If any one wants more info the other readings let me know and i will post them. I ordered the part and will install Wednesday and will let you know how it turns out.

Hi all! I'm looking for input if anyone has experienced this problem I have with my A/T on a 1991 BMW 735il. I put it in reverse and it doesn't engage. I don't get a Transimission Program telltale display but it still works fine and shifts in all of the forward gears. Someone told me it might be a dead rear brake band but I don't know. I also would like to hear opinions on a rebuilt tranny vs. used ones. I get different schools of thought with this ZF unit. Thanks.

Replying to: bmw735il (Jan 22, 2007 2:10 pm) You might very well consider plugging in a good used one. It'll cost half the price or less and if you buy from a good wrecker, who bench tests his units, you're probably fine. The transmission itself is a sturdy one. So if I were in your shoes, I'd opt for a warrantied used unit if your car were close to mint condition, or if it's got some other cosmetic or mechanical issues, I'd just junk it and go buy another 735iL for $3,500--$4,000 bucks and work from there. You should be able to find a nice one for that. These cars are plentiful (at least where I live) and very reasonably priced. |

Replying to: Mr_Shiftright (Jan 22, 2007 9:37 pm) The trouble is, if the poster were to junk it and buy another one for 4000.00, who's to say it too wouldn't dump a transmission in short order? Also, I wonder how many miles that 7 has on it. I wouldn't chance a used one in a high miler. Those are money pits to be sure!
