Default 1988 Mustang GT, transmission problems: T5

Hey guys,
I have the "wonderful" T-5 in my '88 GT, and everytime I go to put it in reverse, it grinds. Very seldom can I get it in without it grinding. Any ideas as to why it is doing this? all other gears are fine, a little stiffer going into gear but then again I have a ZX2 with a 4-banger, so I have been used to a feather clutch and smooth gears. Anything would be helpful, thanks in advance!

Try putting it into first, and then reverse without lifting the clutch.
If it's hard to shift, the cable might be stretched, or the junk plastic linkage stripped.
Also, you didn't just change the tranny fluid did you? It takes auto tranny fluid.

I will have to try the 1st to reverse and see what happens, but no it hasn't been changed yet. I didn't know it took auto fluid, why is this?

I tried putting it into 1st first, and then into reverse and it worked!!Then I just tried to go into reverse without going into 1st first and it wanted to grind again, but doesn't when I go into 1st, then reverse... what is happening?

You always should put it into a higher gear then reverse I always use 5th because it is closer to reverse thats what my tranny rebuilder told me

Something with the synchros. It's normal though.
They just do take auto tranny fluid. Gear oil style manual fluid will make it hard to shift into gear, and eventually toast the tranny.
Sounds like you're good to go.

Hey thanks a lot meangreen, I'm just happy it works fine now (so far)
But any suggestions as to what kind of tranny fluid I should put in? I keep getting mixed oppinions as weather I should use just the Mercon/Dextron III, or throw some synthetic in there once I drain it.
Some say synthetic is the way to go, others say steer away from that.
any help on this would be appreciated!

I said this in your other thread but I will elaborate here. Mercon/Dexron III or GM Synchromesh would be the way to go in my opinion. Tremec recommends Synchromesh. Ford recommends Mercon/Dexron III.

Most synthetics also have some detergents in them that can wear away at SOME synchro facings. In addition to this, synthetic lubricant can be "too slick" at times. The synchros have to catch each other and slow the gears down enough to mesh properly. If the synchros are unable to achieve that friction shifting becomes harder. Using the synthetic (while you would THINK it would help) can actually hurt the synchros in the long run and COULD result in a toasted transmission.

I have always stayed away from Synthetics in my transmission after a bad experience using RP Synchromax. I use it in the rear differential and the engine, but not in the trans.

OK now we're talking, this is the info I wanted to have. Thanks for explaining it out, it's exactly what I needed.

Just for clarification as to why it grinds going straight into reverse on the t5's it is because there is no synchro's for reverse. So just always go into one of the other gears first, then into reverse, I always use 5th also.

Good thread for T5 info

Thanks for the clarification! I was actually still trying to find out why, thinking it may have been just my tranny.

Bad 2nd gear synchro. Fix is replacing the synchro. A big job not for a novice. This is my 3rd Fox body with T5. I've lost the 2nd gear synchro in all of 'em. It's because banging 2nd gear is so much fun!!! My solution is a new T5 World Class.
