Hi guys,



I just got done driving back from getting my transmission oil change (did it myself), but now I am having major problems shifting.



The tranny is really hard to shift into gears sometimes. And whenever I try to go from 4th to 5th gear, it will pop out on its own. And the worst thing that happened to me on my way back, I was stopped at a light, and I was going through all the gears clutch pressed the whole time. Somehow it went into reverse even though I didn't select reverse. I had it stuck for a minute or so (the whole time traffic is zooming past me). I waited till it was clear behind me, and I reversed into the center lane. Eventually I managed to force it out of reverse and into 1st.



Now my question is, did I overfill the transmission fluid? I dont see how cause I used the how-to on Rob Robinettes page, and it specified 3 quarts of Redline MTL. and it overflowed after about 2.5 quarts.



I did have trouble locating the proper fill hole. I unscrewed a small 10mm (?) screw which was pretty long and half thread and half unthreaded. I removed another 12 mm (?) screw at the very top front of the dirvers side thinking it was the fill hole (my fill tube was to small for the other hole). I eventually undid the square peg with a 14mm box wrench. And this looke to be the right on, cause I just referenced it to the scuderiaciriani online shop manual.



Now, according to Robs how-to page and the Scuderiaciriani page I did all the right steps. The only tihng I did was remove the that screw at the top-front (drivers side) of the tranny, which I put back. There didn't appear to be anything on the other side of the hole to me.



Also, couold it be a synchro problem? I'm not very transmission knowledgable, but how could changing the tranny oil cause this problem? I did notice that the first bolt I removed from the tranny must have been the small tranny drain (long small screw half threaded half unthreaded). When I removed that screw none of the old oil spilled out. Will draining out some of the oil temporarily solve this problem? that is until I get the synchro fixed. That's if the synchros really are the problem.



Could it have been the type of tranny oil I used? (Redline MTL). Is this normal and will it go away? or is there a fix for this? Until I fix this problem, I wont be able to use 5th gear and I risk getting stuck in traffic again, so any help would be appreciated.

 

Hello again,



I just found out that I did not remove the other drain plug. Someone pointed this out to me and I double checked on the Ciriani site, and I did not touch the small peg at the very bottom.



I'm gonna buy another quart of Redline MTL and redo this process. I will reuse the MTL in there already, and this time I will drain the correct plugs, and hopefully this should fix the problem.



what do you guys think?

 

What weight fluid did you use?



I don't know if you got the right fill holl to be honest, 2.5 seems light. The fill plug should be on the drivers side of the tranny.

 

I used the "how-to" on Rob Robinettes site, which was done up by Anon. Per his suggestion I used Redline MTL for the tranny (I also did the differential at the same time with Redline 75W90).



2.5 quarts seemed to be the norm with people and per the online FSM at the scuderiaciriani site I did get the correct fill hole. It was the drain holes which I may have messed up. I got the big one underneath ok, but the smaller drain hole was the one I botched up.



I'm gonna go back to the hobby shop and redo the whole thing again and see what happens.
