went to get some ar walmart and all they had was GL5. is that ok to use and what do those numbers mean

Read the manual for what transmission fluid is acceptable.

Or search the forum.

 

[TRobinson6]

the forum said to use GL4 75-90. i found a GL5 75-90 at walamrt and just wanted to know if gl5 was ok and what gl5/gl4 means

For all those people who find it more convenient to bother you with their question rather than search it for themselves.

After scanning that first Pdf , I would say to use what the manual says, or have the dealer change the fluid. If the manual doesn't say to change the fluid, leave it alone.

GL5 Bad for Transmissions

GL 5 is NOT okay . GL 5 is for rear ends, and can degrade syncro rings in a transmission. GL 4 is what is needed, Smart dealers carry Castrol GL4. Amsoil has GL 4 along with Redline and Royal Purple. I used the Castrol stuff from the Smart dealer when I had my 451. Cost was not that much more. Around here Smart dealers will do mail orders. If you put GL 5 in get rid of it as soon as get some of the correct stuff.

i want to thank the lake person for their 1/2 cent of advice

Nothing wrong with a little google action, I learned about the differences between gl4 and gl5. and the fact that it was written about Corvairs brings back memories of working on those beasts!!

i had an 80 four door and a 65 monza. loved the monza. while i was in the air force a major friend of mine had a project to take a wagon then cut the back door section out all the way across then weld the two halves together and stuff a corsa engine in it. needless to say we did not get it done because nasa grabbed him to develope the water purification system to take pee and turn it in to drinking water.

80 four door?? They stopped production on Corvairs in 1969 ?? I did a few slicing and splicing of Corvairs myself. Had a 1965 front and a 1966 rear convertible only I forgot to natch the plates. Police had a few questions on why the plates didn't match.. Both plates were in my name, but still....They were fun to work on.

If you have any questions about tranny fluid you can ask Caitlyn

Is that supposed to be funny?

sorry meant to say 1960........my first car and was my high school graduation gift. dad was called to vietnam and did not want me driving a leaking unreliable car so got me the 65 just before he left. i went in the air force in 67 and towed it behind my wife's car to Edwards afb in Calif. was there 4 months and got bit by the motorcycle bug so traded it for a used bike. DUMBEST THING I EVER DID!! and my wife never let's me forget it

I had a few corvairs, highest count was 27 at one time. my favorite was my 66 Corsa with the 140 motor. Those carbs were a pain but when they worked right....

I've used Red Line MT 90 on the 2 changes I have done

I had a couple of Corvairs. The most fun was a 1965 with a small block 327 cubic inch 365 hp V8 where the back seat used to be. Sneaky fast but the trans was fragile and the input shaft would break if you looked at it cross-eyed.

Same with my 64 Rampside.. easier to put the motor in, especially with the crown conversion but still tended to break things when you jump on it hard.
