I bought an 86 GXL two weeks ago, and the transmission seems to be slipping. I push the gas peddle and it engages late and ruff. Does someone know what it could be.

 

is it auto or stick? if its stick its time for a clutch if its auto its time to head to the trans shop hope you have a couple grand srry it sux

 

You can get a used one for far less than that. Most people will baiscally give them away. Hell, I've got a good one that was sitting in my garage for several months. I had it hauled off cause no one wanted it, but I can still get it back probably.

 

Its an automatic, but im thinking about doing a swap for a manual transmission, but not sure how difficult it is.

 

if you have to how difficult it is you probly dont really want to get involved but if you have mechanicall skills go for it make a learning expierience out of it im sure there are a ton of write ups on it which will give you endless amounts of information

Check the automatic transmission fluid and see if it's low. My friends truck was acting similarly and after a while wouldn't go into overdrive. Turns out the seals rotted and it was slowly leaking fluid over time until the whole shebang was in trouble. I think he had to get a new torque converter and have all the seals redone.

 

How much will I eventually spend on cash, is it worth it. can I use any manual transmission from 86-91 turbo or non-turbo?

 

No idea on money, but you can use the tranny from any 86-91 NON-TURBO rx7. The turbo tranny is different.

 

actually, I'm pretty sure there's a difference between S4 and S5 N/A tranny's as well. I remember somebody saying the S5's were built a little stronger. But, other than that, they should bolt right up. The 5th gear ratio is different from S4 to S5 as well.. Check mazdatrix.

I have a working auto tranny I'd sell ya if you were in Oregon/Washington

 

I just swapped an s5 manual tranny into my s4 n/a after it blew. This was mainly because I had an s5 tranny locally available, not because I felt it would be an upgrade. The n/a trannies are all in the same class of transmissions that Mazda makes, along with the miata boxes. The T2/FD trannies are of a beefier style that is also found in some Mazda and ford trucks and SUV's (like my friend's 94 explorer).

If you look at sticky about the options, you will see that the s5 has a slightly taller 5th gear. As far as intalling it, it's almost the exact same, except the tranny crossmember is different. If you get an s5 n/a transmission, you need to make sure the transmission includes the crossmember. You should also purchase a new tailshaft seal to make sure it doesn't leak. You can get that from the dealer or Mazdatrix.

I wouldn't attempt a 5 speed conversion unless you are willing to put the car down for many weeks...

 

i dont have the handbook to my 86 GXL, and woould like to know what the normal and sport buttons do. Does someone know where the fuse box is located, my radio has no sound.

 

Where's the search ****'s at..... hehe

 

Holy off-topic posts batman! Why do newbs always post in other people's threads... Anyway, the normal and sport buttons adjust the stiffnes of the suspention, but they likely don't work anymore due to age. Also:

 

Sport and Normal eh? How many splines are on the S4 NA transmission input shaft?
