hey i have a '92 sc300 5-speed with only 83,000 miles on it. when i shift (especially from 1st to 2nd), i feel a little clunk going into gear. the higher the rpm the bigger the feel & vice versa. is this due to low tranny fluid, or the ever fun syncro's. i did notice a small oily spot around tranny like a possible leak or old leak. how do i check tranny fluid, where is the fill hole?

 

Disclaimer: (All from my fading memory) I just did the 6-speed swap on my '95. There is no fluid dip stick for the manual transmissions. As you mention above, it sounds like you could be low on fluid. Check with Lexus as to the brand and amount of fluid to add. The drain plug should be located on the bottom of the transmission. The fill plug should be located on the drivers side of the tranny.

While you're under the car, I'd flush the differential fluid as well. Drain plug is the bottom one. It's a magnetic 8 or 10mm allen head bolt. Fill plug is just above it.

thanks for the info, also how did the 6-speed swap go? was it straight forward? how much was the total swap?

thanks again for the info.

P.S. you're welcome!

 

wow, $5900 in parts is a pretty expensive swap. sounds cool though! good job!

 

It sounds pricey and could be done for less, but it's not cheap putting together a driveline that will hold 800+ hp. Everything but the tranny and LSD is new. That jacked up the price.

Next time, I'd lurk around in the supraforums classifieds looking for deals on clutches, flywheels, tranny mounts etc. Unfortunately, a *good* 6-speed with *all* the parts is going to cost you $$$. Additionally, the 6-speed LSD requires a new rear axel because the pumpkin is narrower than the 5-speed/automatic differential. Consequently, I went with the TT automatic LSD.

Is there much interest in used 6 speeds? I believe I know a guy who can get them from Japan (I am in Australia). What sort of prices do they go for? If it covers costs, I'd be happy to help...

 

apparently (i havent totally researched this) they go for around $1500 to $2000 +/- complete.

 

the clunk could mean not enough fluides for torgueconverter or your tranny is going. mine made the same sound before the tranny went on me. mine only made the sound when i shift from park to drive.

 

Soaringhigh: You're talking about an automatic, he's got a 5 spd.....a few differences.....
I have the weird clunk you speak of when shifting from 1st to 2nd and I'm not gonna wait to find out what it is.
I'm doing a full flush today. =)
