Recent manual transmission change on 95 Sunfire, difficult shifts?

My father and I recently replaced the transmission on my 95 sunfire to fix issues with worn 2 and 4 gear synchros and a gear oil leak on one of the drive axles which eventually led to tranny failure. Anyways, the tranny we replaced it with was originally for a chevy cav (supposedly 100% compatible) with relatively low mileage. The 'new' tranny definitely worked better than my old one but with a stiffer and less forgiving feel on the shifter.

Anyways i've noticed that it's difficult to shift into first gear, as in there is a lot of resistance and it's not so easy to find the sweet spot, which BTW is not on the dead top-left of the shifter but rather a 1/4 inch towards the right of where it should be and there is a noticeable amount of resistance to hit 1st. Also sometimes when shifting into reverse my car will make a low-pitched click sound which makes me feel as if I didnt shift properly (although i'm certain that I did).

A few more details: There is a label on the car that says to use GM Syncromesh but all they had at the store was Motomaster Gear Oil, and I think I purchased the one with the right viscosity rating. Also, could it be possible that I didnt bleed the clutch slave cylinder enough when I hooked it up?

    Did you install a new clutch..? It could possibly be that when re attaching the slave it was preset to the older clutch hense out of adjustment if the clutch is not fully diengaged it will be hard to initially get it to get into gear occasionally followed by a thump try re.bleeding the system and see where that takes you

    The Explorer is a good SUV but changing it can be expensive.. you have to change the trucks computer system along with the transmission because the computer controls shifting ect.. It would cost less to sell the Explorer and buy another one like it that is automatic than to try to change it.. You also can run into smog certification problems if you live in a state that is strict like it is here in California...

  • the fluid type may be related to it but i have to think that the problem is with the clutch actuators, as in the clutch master and slave cylinders. it is still possible that the new trans may have an issue with the shift gates.
