5th gear?

If N, then likely LT95.

If Y, 5th up and to the left - LT77. 5th down and to the right - r380.

Or it could be an LT85.

Take a picture of the box and the serial number if it is a 5 speed.

It is 5 speed. Up and to the right. So probably LT77 however I will take a picture and post when I am back home on Thursday.


Thanks

A 1989 model would be an LT85 from the factory. The LT77 should not have been used in a 90 until the 1991 model year behind a V8.

So I have looked at the transmission and think it may be an LT85


There seems to be serial number on it, its hard to see but looks like PR8 2583 CA


Any idea?

Identifying your Unit

There are three types of 5 speed mainbox, LT77, R380 and LT85 (Santana). The following questions will help identify which type of box you have.

1) Is reverse underneath 5th gear?

If yes, you have an R380. Please go to the R 380 section to see a video of where to find the serial number.

If no go to question 2.

2) Is reverse gear next to 1st gear?

If yes, you either have an LT77 or LT85. Question 3 will identify which one.

3) Is the maincasting black or aluminium?

If black you have an LT77, Please go to the LT 77 section to see a video of where to find the serial number.

If aluminium, you have a LT85, Santana box. Please go to the LT 85 section to see a video of where to find the serial number.
