anyone change synchros before?

[bigbird944]

Hey everyone!

Me again tinkerin with my 44 before takin it back out for non winter months. It bugged me last year cuz of the hard shift to second gear in cooler engine temps. Has anyone changed synchros before? are there any step by step procedures online? is it hard? or am i better off finding a used tranny somewhere else? i think i know of one in ct in a junk yard, not sure how many miles on it but just wondering.. thanks for the help again

what oil are you using in your transaxle?

[bigbird944]

not sure...:/ if a clutch replacement is done does it require taking the oil out of there? cuz i had my clutch replaced recently, didnt do a very good job, didnt do everything required, but besides that if it isnt taken out, how often is it required to be changed? whats the good stuff ppl use? any procedures online?

Clueless on transmissions still but learning! thanks a lot!

try putting some redline manual transmission oil in there. it did wonders for the shiftin in my '83. shifted like butta afterwards.

My '87 with 61k (when i got it) was hard shifting into 2nd also. I switched to Redline synthetic like nynor and it helped, but did not solve the problem. I still need to double clutch for the first mile or so otherwise it grinds momentarily before it engages.

Changing the synchros is not for the inexperienced. It requires alot of knowledge of shims and some special equipment to do it. I would NOT undertake it on your own if you have no experience with transmissions.

Fluid should be changed every 50-60k miles.

I found the synthetic oil to be an improvement, that and careful allingnment of the awkwardly designed shift rod. When I traded in my '44 they put synchro's in it. Everyone knows how to baby their own ride, I could shift mine w/o any grinding, yet I wish I had experienced the last two driving years with new synchros, if you intend on keeping it I'd replace them.

However....

Having someone rebuild your transmission is very expensive. Even doing it yourself is going to cost you. Assuming you have your own gear pullers, presses and an oven that you can heat parts up in without your spouse/mom/room mate killing you. Try changing your trans fluid before you start throwing money at your transmission. Like many, when I bought my first 944, is was difficult to get into second when cold. I changed to "quality synthetic" and while my trans is still noisy, 39K miles later, it still shifts nice. Pelican and Paragon Products both sell good trans fluid. Good luck, keep us posted.

awesome thanks for the info! it def. helps a lot.

How do i change the tranny fluid tho? im guessing there's a bolt somewhere similar to engine oil, then again how do u fill it back up? any procedures online anybody know of? I'll def. keep ya posted, this sites incredible i dont know what id do without it

Thanks again,

There are two plugs on the side of the transaxle. You will need a large 19mm? hex head socket. Remove the lower plug to drain. Replace the lower plug and remove the upper plug to add. Fill to the bottom of the upper hole using your finger as a guide. It is much easier to add fluid with a pump as there is not really a good way to pour it into the opening. Some tubing and a squeeze bottle can be used. Try Clarks Garage website for many maintenance proceedures on these cars.

17mm hex, invest in a socket. The L-key is possible but a pain to use.

Remember to remove the upper plug first! If it's stripped or stuck, you'll at least still have fluid in your transaxle...
